Hello Mika,

Thanks! The dump looks OK to me wrt. the PMC device. However, I think I
found the bug.

Can you try if the below hack fixes the issue?
I’ll give the patch a test and let you know how I get on.

Which fields within the ACPI dump are you looking at? When we boot the same hardware platform / Ubuntu image with the stock AMI BIOS then we don’t see the kernel oops.

-Andy.
