A tracker believed to be a preallocated barrier has been apparently modified 
by another thread.  I believe this should be addressed by the other patch, 
"drm/i915/active: Fix misuse of non-idle barriers as fence trackers".

Reported a few months ago by igt@perf@stress-open-close under 
https://gitlab.freedesktop.org/drm/intel/-/issues/5386, closed as not 
reproducible.  Not a regression, I believe.

Incomplete igt@i915_selftest@live@hangcheck with no serial log is a known 
issue, not related to this change, I believe.

No timeout on infinite __i915_active_wait() this time.

Let me resubmit in series with the other patch.

Thanks,
Janusz
