One thing that would be very useful to confirm is whether you are able to reproduce this on drm-tip. At present I am assuming it is fixed, and am looking for candidate fixes since v5.3

At present I am assuming it is fixed, and am > looking for candidate fixes since v5.3 Thank you for looking into this Chris. How can I reproduce this on drm-tip? This might be obvious to developers but I am just a bug reporter. Is this referring to the "master" version of the drm kernel module? I guess its not possible to temporarily use a newer version of just one kernel module, so I would have to recompile the whole kernel? If that is the case then it is probably too much work for me at the moment. At what kernel version number should I expect this bug to be fixed so that I can report it again if still happens when I have that version through normal updates? Currently I am at `Linux 5.3.6`.

Can you verify with drmtip kernel (https://cgit.freedesktop.org/drm-tip). Feedback from this kernel is needed. If the issue still persists with drmtip kernel please attach the error log(crash dump).

Reporter, Update the kernel to latest drmtip (https://cgit.freedesktop.org/drm-tip) and see if this issue is reproducible.

I also was experiencing the issue, and updated the kernel to drm-tip on Arch linux using AUR package linux-drm-tip-git. Now now longer experiencing the GPU crash.

I still see errors '[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B (start=1419640 end=1419641) time 121 us, min 1431, max 1439, scanline start 1430, end 1441' even on drm-tip kernel. Are those relevant?

They are not relevant to GPU Hangs as this bug for. Please check if it's similar to bug 106107. I will mark this issue as resolved as GPU hang didn't happen on drmtip. Thanks!

If the issue still persists with drmtip > kernel please attach the error log(crash dump). drmtip resolves the problem. Note that a hang remains if boot option i915.enable_rc6=0 is present, which was a proposed (but failed) workaround suggested elsewhere for this problem. (bug 105962)
