dmesg with drm.debug=0x1e
The most reliable way to reproduce this for me is logging in and opening the
Unity dash. The system will appear to hang for a few seconds and then recover.
The hang happens very frequently. Sometimes it never recovers and I have to
reboot.
Tried on Linus' 4.5rc2 kernel and intel-drm-nightly from 2016-02-06 with the
same result. The default Ubuntu 16.04 kernel (4.4.0-2-generic) boots with a
black screen, so I haven't tried any earlier kernels. Attaching the dmesg and
crash dump from intel-drm-nightly.</pre>
