Although the risk may be low, I don't want to risk having my disk or data trashed, especially if it happens in a way that's not immediately apparent. Or to have other issues and not know if it's the HT bug. So I took the advice and turned HT off.

I have an i7 7700K. If I had wanted an CPU without HT, I could have saved $100 and purchased an i5 7600K.

ASRock, please post an official response here as to whether and when this will be fixed via bios updates. Thanks.

http://wccftech.com/intel-hyperthreading-bug-in-kabylake-and-skylake-processors-was-addressed-by-bios-fix-in-april-2017/
The link above has an article which states that Intel provided the fix to MOBO vendors in April 2017.
For one, it would be nice to have seen ASROCK put something out on their forum to let people know.  Don't know if you have ever lost all of your data due to some bug, but I can tell you from experience that it is not at all pleasant.   It would be nice to at least see something as to an estimated date as to when updated bios will be available.
ASUS provided the bios updates, they just let people know that they had not validated the bug fix.  I would hope that INTEL did their due diligence and already did that before they sent it to the MOBO vendors.

To quote from your post:

So Asus is unofficially releasing invalidated UEFI/BIOS updates for this issue at this point. Which also could mean that it is unknown whether or not the new microcode fixes the issue.

There is more to the story than simply, "Here is a post on ASUS site where they are posting that they have bios fixes".

What is ASRock doing wrong?

    As discussed in this thread:

    http://forum.asrock.com/forum_posts.asp?TID=5438&title=intel-microcode-bug

    It is not known at this time if Intel, the only source of processor microcode updates, has provided a microcode update for Kaby Lake that addresses this issue.

    If and when Intel provides a Kaby Lake microcode update for this issue, it will then be added and tested in a new UEFI version, and released.

    The best source of information about this would be directly from Intel.

    What problems with critical tasks have you been experiencing? I have not personally experienced any problems so far, using hyper threading. Sure it can potentially affect anyone, but that it will affect everyone has not at all been demonstrated.

    Actually, bug exists at microcode level which means that affects everyone unless hyper threading is disabled.]]>     Sat, 01 Jul 2017 09:37:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=5474&PID=32067&title=intel-hyperthreading-bug-kaby-lake-and-skylake#32067     <![CDATA[Intel Hyperthreading Bug - Kaby Lake and Skylake : It should not impact most people...]]> https://forum.asrock.com/forum_posts.asp?TID=5474&PID=32004&title=intel-hyperthreading-bug-kaby-lake-and-skylake#32004 Author: MX16

    It should not impact most people unless you do heavy parallel loads (Such as compiling software for example), or if there's a program that is heavily parallelized and uses a certain set of instructions and loops.

    I did encounter it and it screwed my encrypted SSD, but I do keep regular system backups so no big deal really.

    I am interested in knowing if ASRock will push updates to their z170 and z270 mainboards though, since they're all affected unless they have the May 2017 microcode included on a very recent update, and the fix is really provided by Intel for Linux in microcode since May.]]>     Fri, 30 Jun 2017 12:49:59 +0000 https://forum.asrock.com/forum_posts.asp?TID=5474&PID=32004&title=intel-hyperthreading-bug-kaby-lake-and-skylake#32004     <![CDATA[Intel Hyperthreading Bug - Kaby Lake and Skylake : Hello, I am using the Z270 Taichi...]]> https://forum.asrock.com/forum_posts.asp?TID=5474&PID=31999&title=intel-hyperthreading-bug-kaby-lake-and-skylake#31999 Author: sotong84

    Tomshardware had an article about a hyperthreading bug that has been found in Kaby Lake and Skylake processors.    
    I don't see anything in any BIOS updates with anything about it nor do I see any posts in the forum.

    I have the ASROCK Z170 Extreme 7 + motherboard.    Anyword on when there might be a bios fix??
