I have a server thats been running fine for a year or two lock up a few

The /var/log/messages after a lockup last night is appended to this

hardware is a pretty typical server, Supermicro X8DTE-F motherboard,
dual Xeon X5650, 48GB ECC memory, LSI SAS 2008 for the boot disks,
and LSI MegaRAID SAS 9261-8i for the data volume. Lots of 3TB disks
in a raid60. Primary application is BackupPC v3.3.0 (from EPEL), it
also has an NFS export (also used for backup purposes).
Runs CentOS 6.latest (kernel 2.6.32-431.11.2.el6.x86_64). X is not
loaded (inittab level 3). selinux is permissive, iptables is not
loaded. this server is on a corporate internal network, 1 Intel
82574L NIC configured with static IP, 2nd one is not in use.
The lovely Supermicro 82574L bug! There was a similar thread about a
month ago:

The short answer that's worked for me: Add pcie_aspm=off to your
boot-time kernel options. I've also started running the kmod-e1001e
package from elrepo.org.
Also, if MSI-X isn't already turned off in the BIOS, others have
suggested making sure it is.
