I have heard of HP/Compaq Proliant servers having similar problems, 
random reboot or system hangs, seems te be a kernel bug from upstream, 
take a look at these bugzilla tickets
https://bugzilla.redhat.com/show_bug.cgi?id=494114
https://bugzilla.redhat.com/show_bug.cgi?id=470202

The two problems have been solved as from test kernel 2.6.18-144,
