AMDGPU screen/system freeze.

In case anyone is experiencing a screen/system freeze once in a while with AMDGPU, it is possibly caused by: https://bugzilla.kernel.org/show_bug.cgi?id=204181

There would seem to be a patch already, but the current kernel (5.3.1-arch1-1-ARCH) has likely not received that yet, as the bug is still present.

This is more of an info post than anything, but if someone has some quick fixes (kernel flags, etc.) available, please, do share.

Re: AMDGPU screen/system freeze.

I'll occasionally get this lockup-but it manifests itself when waking up...totally random, and I can't think of a way to reproduce it reliably.

I'll just ssh in and reboot the machine gracefully.

Re: AMDGPU screen/system freeze.

@selendym that bug report references multiple patch series:

https://patchwork.freedesktop.org/series/64505/ is queued for 5.3.2 and applied to mainline.
https://patchwork.freedesktop.org/series/64614/ and https://patchwork.freedesktop.org/series/65192/ not queued for stable but have been applied to mainline.

Re: AMDGPU screen/system freeze.

@loqs
The one I'm experiencing crashes with "RIP: 0010:dc_stream_log+0x6/0xb0 [amdgpu]".
The third one in https://patchwork.freedesktop.org/series/64505/ may have something to do with that, hopefully.
