title="NEEDINFO --- - [SNB regression vsync] WAIT_FOR_EVENT hangs"
href="show_bug.cgi?id=67092">bug #67092</a>
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).</pre>
