For the ERROR the kernel is the important part. I can be that it's
triggered by userspace doing something funny (and likely, sinc there's a
good chance you're hitting a less well tested path when crashing). But
it's a kernel issue.

To track the kernel issue down can you please boot with drm.debug=0xe
added to your bootline, reproduce the issue and then attach the complete
dmesg?

Thanks, Daniel
