Interesting...

First, is vanilla 2.6.24 kernel OK? Or 2.6.24.4, even.

You can extract .config from ovz kernel in /proc/config.gz
and recompile vanilla kernel with it (ignore all missing
options messages), then collect "dmesg" output from working
and openvz kernel. Differences between them should sched light
on this issue.

If you can't or won't recompile kernel, post dmesg and .config
from any kernel that doesn't drift.

Attach both dmesgs here, or in bugzilla.

P.S.: acpi=off is crude hammer, something in openvz should
be fixed.
