Might be related to bug #67092

Here is how I reproduce it.
1. switch to external displays via xrandr
2. go about my day (play videos, go to websites, whatever) and switch back to the LVDS display
3. suspend
4. unsuspend and go to websites (heavy ones do this more, google plus, google maps, youtube sometimes as well).
5. hang/lockup

I have NOT been able to get the error state stuff from a locked up system, only if it recovers (which it does 80-90% of the time I think).

Yes, the hang is #67092 and I would say the hard lock is #62373.
