--- Comment #2 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.
512 ��� [ 1.053284] pci 0000:01:00.0: can't claim BAR 6 [mem
0xfffe0000-0xffffffff pref]: no compatible bridge window
513 ��� [ 1.053289] pci 0000:00:15.0: BAR 0: assigned [mem
0x4010000000-0x4010000fff 64bit]
514 ��� [ 1.053365] pci 0000:00:15.1: BAR 0: assigned [mem
0x4010001000-0x4010001fff 64bit]
515 ��� [ 1.053379] pci 0000:00:1f.5: BAR 0: assigned [mem
0x6ea20000-0x6ea20fff]
516 ��� [ 1.053389] pci 0000:01:00.0: BAR 6: assigned [mem
0x6e960000-0x6e97ffff pref]
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:
347 ��� [ 0.913731] ACPI BIOS Error (bug): Could not resolve symbol

Hope this helps.
