[...] I can reliable generate such lines in Xorg.0.log with KWin cube desktop effect.
Rotate screens with mouse wheel or screen switcher => new entry in Xorg.0.log. If it happens I notice ('see') flip delay.
I was only able to reproduce it a couple of times even with that, but not at all yet with the patch below. Does it help for you as well?
Will try in the next run.
My daughter generated kernel crash for us.;-) See would open up a zoom image in Konqi of a new Waveboard for here girl friends...
But I could only take images with my mobile. kernel BUG at drivers/gpu/drm/drm_irq.c:976!
I was able to reproduce all these issues, and the attached three patches fix them for me. Please let me know if you can still trigger the panic or the diagnostic error messages in patch 2 somehow. If everything works fine for you as well with these, I'll submit them with the error messages in patch 2 changed to debug messages.
