Comme= nt # 47 on bug 10232= 2 from Andrey Grodzovsky 
Created attachment 141174 [details] [review]
add_debug_info.patch

A am attaching a basic debug patch, please try to apply it. It should give a
bit more info in dmesg whe VM fault happens. I wasn't able to test it on  my
system so it might be buggy or crash.

Reproduce again like before with the cmd-trace like before and once the fau=
lt
happens if possible try quickly run=20

sudo umr -O halt_waves -wa

and only if you still have running system after that do the=20
sudo umr -O verbose -R gfx[.]

The driver should be loaded amdgpu.vm_fault_stop=3D2 from grub
Also check if adding amdgpu.vm_debug=3D1 makes the issue reproduce more qui=
ckly
