The gpu was never the same after the hang in kms_draw_crc, and it ended up being declared wedged when a reset failed shortly after in perf.

    igt/gem_gpgpu_fill: Check for GEM before use
    
    As we need GEM and the GPU to do a GPGPU fill, we should check that it
    is operable before using -- skipping rather than failing when the device
    is wedged.

Closing this bug, this issue not seen since 1 month.

15 rounds ago this issue occurred only once with drmtip. So, this issue is closed.

Comment 4 Martin Peres 2018-08-30 12:34:16 UTC

I will also add the following (old issues) here, since the signature matches and it stopped right after the actual fix was committed.
