Comment 1 Chris Wilson 2018-10-15 11:11:00 UTC 
*** Bug 108367 has been marked as a duplicate of this bug. ***
Comment 2 Chris Wilson 2018-10-15 11:12:10 UTC 
Notably, on both it is an idle vecs that explodes. Very, very suspicious hw behaviour.
Comment 3 Chris Wilson 2018-10-15 19:35:23 UTC 
Possibly?

commit 9d3eb2c33f03432a25a6a3ab3177f839f25cbaf5 (HEAD -> drm-intel-next-queued, drm-intel/drm-intel-next-queued)

    drm/i915: Hold rpm wakeref for debugfs/i915_drop_caches_set
    
    Since we peek into HW state and poke around, it behoves us to acquire a
    runtime pm wakeref beforehand.

Bug was unfortunately hijacked by a separate issue.
Comment 9 Francesco Balestrieri 2018-12-11 13:28:23 UTC 
The last ten occurrences happened on average daily, now not seen for 1 week and 4 days. I'm going to close it, shout if you disagree.
