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.
