Comment 2 Chris Wilson 2019-01-04 16:35:56 UTC

Since the gpu should not have hanged there anyway (it's falling over the readonly faults), its state is indeterminate and that it tripped over itself may just be more undefined behaviour.

First fix the known issue and see what remains.

This particular bug got fixed 3 weeks ago, apparently! No idea what changed, probably a rework or a new bios.

In any case, closing!
