I've been experiencing this as well for about a week or so.

It's hard to say whether this is a symptom of this bug - which is
rapidly turning into a kitchen sink catch-all for problems that cause
crashes - or something independent. I haven't gone looking for a more
specific ticket against X, but if anyone runs across one, post a
reference to it here.

The best bet for getting these crashes resolved is to group together
reports that all share very specific symptoms, like the originally
reported "Clocksource tsc unstable" log entries, and let the developers
work their way through eliminating each specific symptom.
