More of the same hang. At least now it seems to recover, but these GPU hangs are from the drm-next of mid-September; the branch I have with those changes carved out is rock-solid.

Do you see the same issue from drmtip branch?

Unfortunately I cannot use drm-tip as it breaks power-management during S0 suspend (see bug https://bugs.freedesktop.org/show_bug.cgi?id=111909).

Can you disable GUC and reproduce the issue?

You'd asked me to disable GuC a while ago for another manifestation of this same bug and it made no difference: https://bugs.freedesktop.org/show_bug.cgi?id=111920

I'm in the middle of a dev cycle right now and can't take time yet to attempt to see if the bugs in drm-tip are fixed, so I've been running Linus' master with all drm/i915 changes since late September yanked out (which runs perfectly now).

Maybe on the weekend I'll pull drm-tip and see if this and the power-management issue (https://bugs.freedesktop.org/show_bug.cgi?id=111909) work any better, though.
