Comment # 2
on bug 1190854
from Hadrien Grasland
Cross-checking the dmesg logs before the amdgpu failure, I also found this,
which sounds possibly related, although this is getting beyond my level of PCI
jargon proficiency so I can't analyse it in depth.

Here it seems that the BAR 6 from the AMD GPU tries to get to one memory-mapped
location, and ends up in another due to a "bridge window" issue. Not sure if
the amdgpu driver is meant to tolerate this well.

Also, even earlier in the log, there are some ACPI errors that come from the
PCI Root Bridge [PC00], which may or may not be related to the power management
errors that I see later on:

Hope this helps.
