I am seeing random reboots after installing Xen 3.2.1 (running with
linux-2.6.18-8 pulled from a few days ago). So far, the reboots only
happen if I have enabled cpufreq=dom0-kernel and actually run
frequency scaling (such as with the ondemand governor). The reboots
only happen after a few hours. The machines seem to be stable if I
pass the cpufreq option to Xen but disable frequency scaling.

I can't see anything in the log files that looks suspicious right
before the reboot. The worst I have seen are a couple of "Timer went
backwards" error messages but they don't always show up in the logs.
Anything else I should be poking at to figure out why this might be
happening and if there are any potential fixes?

Thanks,
Niraj
