I saw some similarity with bug #93629, but this is not related to any
SCHED_ERROR. Also it is very often, usually chrome triggering it. 
I had problem with this GC, turning off the monitors on startup, but that
problem is now fixed in the latest kernel.

This is a complete hang, and seems to happen quite enough, I will gladly run
any kernel/driver combination to sort this out.
