Core Temp crashes to black screen in Windows 11

[spiritofjerry]

Hello,

Been using Core Temp to monitor CPU temps for the better part of a decade. I have a Thinkpad T14 Gen 2 AMD laptop that was running Windows 10 and Core Temp without issue. Last week, I updated to Windows 11, and launched Core Temp -- instant Windows black screen with the sad emoji. Uninstalled Core Temp and reinstalled, same result. It appears the app has a conflict with Windows 11 and my machine configuration.

Anyone else experiencing this, or am I a fringe case?

Please check the event viewer in Windows to see what was the reason for the BSOD.

No dump file is created. The event viewer just shows a critical error, but there is no information. It's a black screen, total system failure, but no evidence as to what causes it.

My issue is identical to this one: viewtopic.php?t=5835

Can you please export this error (right click on it and Save). Also select display information in English.
Zip it and attach it to your post.
The behavior may be the same, but the reason is most likely different, as the previous problem was fixed a long long time ago.

I'm attaching all errors/critical errors I see after the crash occurs, in the format you requested. Let me know if there is anything else I can do.

Just want to bump this. Any confirmation of the issue? Anything else I can do/report to speed up work toward a fix?

Not yet. It looks like a bug in the driver.
I'm a bit busy with RL and work, so have had no time to look into it yet.
Sadly, with a driver issue, debugging becomes a bit tricky, and tedious. And I don't have a machine on which this problem reproduces to debug it on one of my systems.

I've reproduced this on a Thinkpad P14S (gen 2 amd) and have a workaround. It occurs under these conditions:

- AMD virtualization extensions enabled in BIOS.
- "Enhanced Windows Biometric Security" enabled in BIOS (same place as the above - Security -> Virtualization menu).
- Hyper-V role enabled in Windows 11 (no idea about Windows 10).

If ALL of the above are met you'll get a hard reset as soon as the Core Temp process is started. Or in my case as soon as logging in as I had Core Temp set to autostart.

Easiest fix is to just disable "Enhanced Windows Biometric Security", as who the hell knows what that does anyway.

Thanks to the author for such a useful app!

I can confirm the issue is resolved by simply disabling Hyper-V in Windows (I'm not currently using it), but I'm sure also disabling the Enhanced Biometric Security setting would also work. Thanks for the workaround, it's nice to actually be able to use the app again. Hopefully there can be a proper fix in the pipeline.

I have a P15v Gen 3 (AMD) & encountered a similar issue after doing an in-place upgrade to Windows 11 22H2 from Windows 10 22H2.
Version of Coretemp used is 1.18 (32 bit)
The computer can boot to the Windows log-in screen but it crashes with a SYSTEM_SERVICE_EXCEPTION BSOD after one log in to Windows.
ALSysIO64.sys fails to load.
Disabling "Enhanced Windows Biometric Security" in the BIOS still works as a workaround.
