Hi, we got reports from our freedesktop gitlab[1] that this commit:

- drm/amdgpu: attach tlb fence to the PTs update

Has root caused GPU hangs during video call or workloads like llama and
Steam. See [1] for details. The symptom is constant MES buffer full
message:

Jan 06 15:42:34 fw13 kernel: amdgpu 0000:c1:00.0: amdgpu: MES ring buffer is 
full.
Jan 06 15:42:36 fw13 kernel: amdgpu 0000:c1:00.0: amdgpu: MES ring buffer is 
full.
Jan 06 15:42:39 fw13 kernel: amdgpu 0000:c1:00.0: amdgpu: MES ring buffer is 
full.

The commit is f48f5bcb6e5a in Questing.

Unfortunately, I don’t have a reliable way to reproduce it, and it seems
to take hours or even days to manifest, making it hard to file an SRU.
But if there happens to be any user report similar issue to you, the fix
is [2].
