Notice the loss of dmesg, and lost information as to what took the machine out.

How about if we mount the fs with sync?
Comment 2 Martin Peres 2017-06-15 11:27:16 UTC
Good idea Chris! Tomi will try to remount the filesystem with sync before running IGT.

I will close this bug for now, it used to happen every day, but we got no new occurence since May 24th!

    drm/i915/g33: Improve reset reliability
    We improved the reset reliablity on gen4 with
    stopping all engines before commencing reset, in
    commit 2c80353f3cd0 ("drm/i915/g4x: Improve gpu reset reliability")
    Evidence indicates that this same trick works with g33.
Comment 4 Ricardo 2017-06-27 14:16:31 UTC
Closing bug since there is no new failures
