I'm not sure if it was same signature twice. I had two lockups, but
IIRC only investigated one.
Not really a demo mode. I can put plane on autopilot, but eventually
gas runs out. (And I guess window needs to be visible for test to be
effective.) I tried today, but it did not crash.
Do you have something else I could run to do the testing?

Recent kernels I'm running are self-compiled.

If I can reproduce it, it makes sense to create bugzilla entry.
