Serious unknown changes coming with Patchwork_10331 absolutely need to be
verified manually.
If you think the reported changes have nothing to do with the changes
introduced in Patchwork_10331, please notify your bug team to allow them
to document this new failure mode, which will reduce false positives in CI.

Those failures are there even without my patches (see
https://patchwork.freedesktop.org/series/40112/). Is there an existing
bugzilla? In the meantime, I'll have a look to see if I can find what's
causing this.
inject_preempt_context() fails when talking to the guc, catastrophe
ensues. As shown above it's quite reliable after a fake suspend/resume,
but it also happens during normal preemption (the preemption smoketest
was added to exercise this issue).

Do you consider this a blocker to getting the patches merged?
BTW, on my SKL even with the preemption smoketest I didn't see any issue
on the tree I based the patches on (from Monday) and I only see issues
after:
b16c765122f987056e1dc9ef6c214571bb5bd694 is the first bad commit
commit b16c765122f987056e1dc9ef6c214571bb5bd694

drm/i915: Priority boost for new clients
However I don't get any error logs out (the machine just dies) so not
sure if it is the same issue or not. with that patch and the 2 following
related ones reverted I've been running the live selftests in a loop
without issues. Is this the bug you mentioned or are those possibly 2
different issues?
Thanks,
Daniele
