The news will apparently get worse before it gets any better for Intel, as the company updated their security recommendations for the Spectre/Meltdown patches for affected CPUs to address post-patch system restart issues. Specifically, Intel notes that issues may be introduced in some configurations with the current patches, though the company does not recommend discontinued use of such updates:
" Intel recommends that these partners, at their discretion, continue development and release of updates with existing microcode to provide protection against these exploits, understanding that the current versions may introduce issues such as reboot in some configurations".

The recommendation section of the security bulletin, updated yesterday (January 17, 2018), is reproduced below:
- Intel has made significant progress in our investigation into the customer reboot sightings that we confirmed publicly last week
- Intel has reproduced these issues internally and has developed a test method that allows us to do so in a predictable manner
- Initial sightings were reported on Broadwell and Haswell based platforms in some configurations. During due diligence we determined that similar behavior occurs on other products including Ivy Bridge, Sandy Bridge, Skylake, and Kaby Lake based platforms in some configurations
- We are working toward root cause
- While our root cause analysis continues, we will start making beta microcode updates available to OEMs, Cloud service providers, system manufacturers and Software vendors next week for internal evaluation purposes
- In all cases, the existing and any new beta microcode updates continue to provide protection against the exploit (CVE-2017-5715) also known as “Spectre Variant 2”
- Variants 1 (Spectre) and Variant 3 (Meltdown) continue to be mitigated through system software changes from operating system and virtual machine vendors
- As we gather feedback from our customers we will continue to provide updates that improve upon performance and usability
Intel recommendations to OEMs, Cloud service providers, system manufacturers and software vendors
- Intel recommends that these partners maintain availability of existing microcode updates already released to end users. Intel does not recommend pulling back any updates already made available to end users
- NEW - Intel recommends that these partners, at their discretion, continue development and release of updates with existing microcode to provide protection against these exploits, understanding that the current versions may introduce issues such as reboot in some configurations
- NEW - We further recommend that OEMs, Cloud service providers, system manufacturers and software vendors begin evaluation of Intel beta microcode update releases in anticipation of definitive root cause and subsequent production releases suitable for end users
Intel recommendations to end users
- Following good security practices that protect against malware in general will also help protect against possible exploitation until updates can be applied
- For PCs and Data Center infrastructure, Intel recommends that patches be applied as soon as they are available from your system manufacturer, and software vendors
- For data center infrastructure, Intel additionally recommends that IT administrators evaluate potential impacts from the reboot issue and make decisions based on the security profile of the infrastructure
Intel has worked with operating system vendors, equipment manufacturers, and other ecosystem partners to develop software updates that can help protect systems from these methods. End users and systems administrators should check with their operating system vendors and apply any available updates as soon as practical.

** Edit by Allyn **
Digging further into the model options / specs, it appears that some of these models will have an optional 16GB (smaller of the two) variant of Optane storage installed as a Storage Accelerator. This accelerator appears to be configurable with either an NVMe (NAND) SSD *or* a HDD. Intel will most likely overlay this cache using their RST Driver, as that infrastructure was put in place way back in 2011 when they introduced Z68 RST Caching. The 2011 version of this caching was an attempt to overlay a small SATA SSD onto a HDD, and while it was effective, the rapid adoption and sales of low-cost MLC SSDs quickly outweighed the need for such a cache as a boot volume.
XPoint should offer enough of a performance boost (particularly for very small random access) to make for effective performance gains even over NVMe SSDs. Depending on how Intel tunes their RST driver to employ XPoint, we might see some impressive benefits, especially if the non-volatility is taken advantage of. Near instant wake from hibernates if the hiberfile is mostly cached on wake/boot, as an example.
Something else worth considering, that is not present in the above leaked specs, is that Optane will very likely be able to handle <4KB random accesses extremely well (XPoint is byte / word randomly writable / addressable). The key question is if that is possible in its first generation implementation, which we should know more about shortly after CES.
** End edit **
We won’t have detailed information about hardware (specific CPU models, etc.) until CES, so stay tuned!

Tagged: update, Skylake, gigabyte, bug
Gigabyte has released UEFI updates today which will resolve the freezing issues on Skylake seen in certain circumstances of Prime95 and GIMPS processing. Just head over to their download site and enter in your motherboards model and download the new UEFI, or BIOS if you prefer the old terminology.
As a bonus you may receive the ability to use higher clocked RAM, see any stability issues fixed or better performance from integrated components such as LAN or SATA. Their update process is easy with none of the stress that once accompanied updates via floppy disjs or masks and UV light. We can neither confirm nor deny these updates will also resolve unwanted ear hair growth.

Tagged: windows 10, windows, update
I cannot help but think of Adobe Creative Cloud when I read Peter Bright report on Windows 10's update schedule. Previously, we would have general security and stability updates for Windows with the occasional Service Pack to roll updates together and sometimes introduce new features. Now, users might be able to choose how quickly to apply these updates, opt-out of everything but security patches, and/or accept experimental features.
I say "might" because this is not technically a Microsoft announcement. Windows 10 has a new user interface, along with a few registry entries, for users to choose update frequency and development branches. The company would not say whether the Windows Insider program would continue after release, but the assumption is that it would be around for enthusiasts and IT testers to prepare for (and influence) upcoming changes. Think of it like an OS equivalent to the prerelease versions of Chrome and Firefox.
The article also suggests that the version number could periodically increase and that this initiative would replace Service Packs.
And this is where it feels a lot like Creative Cloud. Rather than waiting for an 18-month release schedule, Adobe is able to push out features at their leisure. Initially, I expected that this would lead to stagnation, but I do not see many complaints about that. On the other hand, it also pushed Adobe's software into a subscription service, which is something that people have been anticipating (and fearing with some) for quite some time now. Alternatively, it could be setting up Microsoft to subsidize Windows with online services. Either way, it could make it harder for them to justify incrementing the major version number.

In other Microsoft news, the company is rumored to be working on its next generation operating system. Codenamed Windows Blue, it will be a low cost upgrade for existing Windows users that will be based on a subscription service for updates.
Details are extremely scarce at this point but it does seem like a probable move from Microsoft. It does seem like Microsoft has been moving in that direction for some time now. According to The Verge in reporting on sources in the know, Windows Blue will keep the Windows 8 name for branding purposes but the OS will receive a new SDK, UI changes, and performance tweaks during yearly updates. The updates are due in mid-2013, and the Windows Blue update service will span from Windows 8 to Windows Phone (Windows Server was not mentioned). Oddly enough, with the Windows Blue update Microsoft will stop accepting new Windows Store applications built to run on Windows 8. The Windows Store will continue to allow existing Windows 8 applications, but will require developers to rewrite their applications using the new SDK in order to get them on the Store for users running Windows Blue subscription service.
It is a lot to take in, and there are many unknowns at this point. Do you think Microsoft has a good idea with the yearly subscription model, or will it cause backlash from users used to the way Windows has worked for years. Especially those that buy an OEM system with a pre-installed OS and use it until something breaks. Will they be receptive to yet another subscription service for an OS that traditionally has been a one-time purchase?
Assuming it is a good idea, how much would you pay for yearly updates? Will the Windows Store be enough of a success to essentially subsidize the development cost and allow for cheap pricing on the subscriptions?

Tagged: update, tablet, root, nook tablet, modding, kindle fire
Both the Kindle Fire and Nook Tablet have been given recent software updates. These updates were stated to improve performance and squash minor bugs. Unfortunately, in addition to these improvements, the automatic updates contained a “fix” that removed the ability to gain root access to the tablets. Specifically, the updates in question were 6.2.1 for the Amazon Kindle Fire and 1.4.1 for the Barnes and Noble Nook tablet. What is even more unfortunate is the fact that these updates are pushed to the devices automatically. The Kindle Fire and the Nook Tablet will update as soon as they are connected to a WiFi hotspot, for example.
The Nook Tablet gets an even worse deal, however. In addition to the removal of root access, users will not be able to side-load other Android applications. The ability to side-load other Android apps was likely a deciding factor for many when comparing the Nook Tablet and the Kindle Fire, as well as Nook eReaders traditionally being more hackable and mod-friendly.
Currently, the only way to keep root access on both tablets is to stay off of WiFi connections or disable automatic updates in the case of the Nook Tablet. If your Nook has already been updated, XDA has somewhat of a solution. While you will not be able to use the 1.4.1 update, you will at least be able to have root access, mod, and side-load applications to your hearts content. Their fix involves rolling back the 1.4.1 update to the previous 1.4.0 update and is detailed here.
Kindle Fire users will need to either stay off of WiFi hotspots or in the case of an already updated tablet wait for a workaround from the modding community.
The restrictions placed on both tablets are not likely to please users, especially buyers of Nook tablets as Barnes and Noble's eReaders have traditionally been friendly to modders. On one hand, users want options and the ability to install third party applications. On the other hand are Amazon and Barnes and Noble selling their tablets at a loss and needing to make up money by convincing people to buy into their software and services (their applications, bookstore, et al). For aspiring modders, patience is key as workarounds are likely to emerge soon. Until then, getting a tablet for cheap will have to suffice ;).
Where do you stand on the issue, do you think removing root access was the right move for Amazon and B&N? Let us know in the comments!
