--- Comment #47 from Andrey Grodzovsky andrey.grodzovsky@amd.com --- Created attachment 141174 --> https://bugs.freedesktop.org/attachment.cgi?id=141174&action=edit 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 fault happens if possible try quickly run
sudo umr -O halt_waves -wa
and only if you still have running system after that do the sudo umr -O verbose -R gfx[.]
The driver should be loaded amdgpu.vm_fault_stop=2 from grub Also check if adding amdgpu.vm_debug=1 makes the issue reproduce more quickly
