Sorry, but that log isn't really that useful.

It's not complete, please attach the *whole* kernel output (first line should
start with "Linux version").

Please make sure the cmd line args include drm.debug=0xe.

Please use slub_debug without any further options, or if you have a good reason
to think those should be enough, please explain.

Also, I think it would be good if this bug contained more detailed instructions
on how to reproduce the problem.
