The pronouncement from live_workarounds about the nature of the failure is a little misleading. The root cause here is the unrecoverable reset (same as live_hangcheck), but what's more interesting in this case is the subsequent oops after we have wedged the device... That shouldn't occur -- wedging should be fail-safe!

commit 01f8f33e9986aed42a0366704f715cf30e7cb41c (HEAD -> drm-intel-next-queued, drm-intel/for-linux-next, drm-intel/drm-intel-next-queued) Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Jul 17 09:41:21 2018 +0100 drm/i915: Always retire residual requests before suspend If the driver is wedged, we skip idling the GPU. However, we may still have a few requests still not retired following the wedging (since they will be waiting for a background worker trying to acquire struct_mutex). As we hold the struct_mutex, always do a quick request retirement in order to flush the wedged path. Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107257 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180717084121.28185-1-chris@chris-wilson.co.uk will reduce this down to the existing bug for the reset failing inside live_workaround: bug 107188.
While the test still fails, WARN_ON(i915->gt.awake) appears to have been fixed.
Can we close this then? Martin?
