Comment 5 for bug 1731796

Happened again. Auto-bug reporting didn't recognize this report as similar, so created bug 1734405

Note - compiz was in Z state (per top), consuming 100% of a cpu (per top) throughout the incident. I was able to login via ssh and look at things.

I don't believe that a stuck compiz process could be caused by soft lockups. So the compiz process *may* be closer to the root cause?
