Public bug reported:
Binary package hint: linux-image-2.6.24-4-server
When I upgrade from 7.10 to hardy my clock simple drift few seconds/min.
With high cpu usage the clock drift 5min or 10min at random!
The problem is consistent with 4 machines (same hardware) I upgraded.
The NTP can't sync the clock and ntpdate running every min drift tons of
seconds.
The unique warning in logs is the infamous "Clocksource tsc unstable
(delta = 732182695 ns)" 5min later the system's boot.
I try "noapic" and "notsc" but the problem persist.

2.6.24-4-server #1 SMP Mon Jan 14 18:47:45 UTC 2008 x86_64 GNU/Linux
When a big change happen in the clock system "freezes" and only returns
to work properly when the cpu diminish their use.
