Subject: Kernel 3.7.2 strange warning and short system hang

Hi,

today I had a strange system hang on one of our new Dell PER620 machines.
I'm running a self compiled kernel, version 3.7.2 with linux vserver patch included.

uname -a
Linux dbhost04 3.7.2-vs2.3.5.5-rol-em64t #4 SMP Sun Feb 3 14:08:37 CET 2013 x86_64 GNU/Linux

15min. systemload between 1-3.


Today the system hangs for some seconds and I got the folling errors in syslog multiple times within one second:

After the last message I got this entries in syslog, too:
Feb 20 15:58:04 dbhost04 kernel: [1464001.755218] CPU18: Core power limit normal
Feb 20 15:58:04 dbhost04 kernel: [1464001.760038] Clocksource tsc unstable (delta = 299966106527 ns)
Feb 20 15:58:04 dbhost04 kernel: [1464001.769627] Switching to clocksource hpet

I searched the archives for this error, but I can't find any solution.
And my second PER620 doesn't show this error until now.

Have you any idea what this problem could be?

Many thanks for your help.
