During another shutdown after heavy usage of the box, the following

This means that BIOS code faulted during RTC settime call. I doubt that
it is related.
On the other hand, it is good that the onfault EFI RT code got tested finally.
Thanks for clarification :)
Any chance of getting a fix for the AMD CPUs in the foreseeable future?
Or should I revert commit 9e680e4005b7 on affected boxes until further
notice (as a workaround)?
I am working on it, no ETA.
Interesting point would be to check on machines of other testers,
if the following hides the problem.

This patch hides the problem for me. The system seems to work better now.
No waiting on reboot, and the webcam works better.
