Re: WHEA-Logger Event 19 / Processor Core / Corrected Machine Check / Internal Parity Error / W541

If you hit start and type “control”, select the control panel, then choose the old programs and features, on the top near the left will be installed updates. Select the update and click uninstall

 

definitely not intuitive

It is very strange on my Windows. There is only Organize-button, no Uninstall, no right-click-menue. I 'm Administrator. Windows 10 Version 1709.

I've seen some assertions that most users of "single user" machines shouldn't have to concern themselves too much with the Meltdown and Spectre vulnerabilities.  However, bear in mind that your browser is a user mode program which itself can run arbitrary code.  I believe these vulnerabilities have been demonstrated to be exploitable through Mozilla Firefox and Microsoft Edge.  Whilst patches may now be available for those browsers, users uninstalling operating system level patches should make an effort to understand if there are other threat vectors.

Same issue on my X1 Carbon (2nd, 20A7005RGE) with BIOS GRET54WW 1.31. After removing KB4056892 everything is good again. Tend to try 1.30 available in support to reinstall KB4056892.

Re: WHEA-Logger Event 19 / Processor Core / Corrected Machine Check / Internal Parity Error / W541

W540 running W10 here - updated the BIOS early January and got the Windows KB update a couple days after - didn't have problems right away, but after a week, started getting BSOD with various stopcodes (video, IRQ) and then found the WHEA event 19's that were logged exactly every minute (sometimes 2 per minute/same time)... Finally found this thread (thankfully) - uninstalled KB4056892 as others have - and my problems have gone away thus far.
Hoping Lenovo posts an update - or MS... I'm sure we're not the only few with this issue.

Hello,

 

For information about the availability of BIOS/UEFI firmware from Lenovo with updated Intel microcode, please see:

 

 

and scroll down to the ThinkPad section. 

 

This advisory is being updated by Lenovo every 1-2 business days and is going to be the best source of information about updates.

You might be taking the least safe route to avoiding problems. That KB addresses Meltdown, and from what I understand that exploit is far easier to implement and there are many examples that have been developed - even in malicious JavaScript.  The problems you had were due to the new BIOS/microcode and that KB together.  Do your own due diligence, but I believe you would be safer with the KB applied after turning off the CVI2017-5715 protection in the registry as described here (or with a utility like InSpectre). Once we get a new BIOS & microcode update from Lenovo, then you should be able to re-enable that Spectre protection.

Thanks, ianw01 -- I needed a quick and dirty fix as my machine would freeze or blue screen after only 10-15 minutes. I'll check out your posted links - thanks!

I'm feeling more confident about my recommendation. Check out this Microsoft page: https://support.microsoft.com/en-us/help/4078130/update-to-disable-mitigation-against-spectre-varian...

Re: WHEA-Logger Event 19 / Processor Core / Corrected Machine Check / Internal Parity Error / W541

I have the same issues with T540p (20BF).

 

I installed firmware 2.30 early January when I was available and it was withdrawn hours after the installation.

Since that I had several unexplained reboots and now I saw the WHEA-Logger 19 events, which led me here.

 

I already downgraded to 2.28, but that did not help.

 

I senserely hope Lenovo will release a firmware update soon.
