Hi,
we keep getting kernel panics on our CentOS 6.3 server, running about 40
KVM virtual machines.
Here's the screenshot of the trace: http://i.imgur.com/yaRyF.png
# uname -a
Linux srv010 2.6.32-71.el6.x86_64 #1 SMP Fri May 20 03:51:51 BST 2011
x86_64 x86_64 x86_64 GNU/Linux
CPU is Intel i7-2600K with 32GB DDR3 ram.
If there's any more info we can provide, please let me know.
Thanks
Mikko

The presence of machine_check() suggests that you have a hardware
problem that the kernel doesn't know how to recover from.
(Although you only sent part of the trace.)

You are in the wrong place - the Red Hat enterprise kernels deviate a lot
from upstream and are very old. Really you need to go back to the Centos
community with it.

This is more like general info/tip: anyone wishing to test the latest
mainline/stable kernels from kernel.org on RHEL systems can do so by
installing kernel-ml [1] from the ELRepo Project. As of today, 3.6.2 and
3.0.46 are available for RHEL-6.
