Hi all,

Saw a long thread on this back in Oct. but did not see if this was
resolved or not.

We are experiencing "hrtimer: interrupt took <huge_number> ns" errors on
the guest console with -smp 2 running on an Intel host. Both are running
2.6.33.3 vanilla. Guest is using kvm-timer, Host is using tsc.

Guest will become completely unresponsive after about 23hrs. Review of
logs after restart shows that the system suddenly shows a system time of
2 weeks in the past.

Not sure what else to report here. I've changed the guest to a single
CPU, and the problem appears to be gone...

Let me know how we can help on this...
