Thanks for the update.
If the first patch prevents the crash from happening, then I'll keep it for
the time being. I have a list of patch "fixes" that get applied to the
kernel I'm testing, such that I can run the tests without them failing for
something that I'm not testing. Otherwise, I'd never get to test my code :-)
Some of theses patches just remove "WARN_ON" because those will cause my
tests to fail. I really don't care if i915 triggers WARN_ON() as my code
shouldn't be affecting it.
