We have several blade servers on an HP BladeSystem. Over the past 2 months we have experienced about 4 spontaneous reboots. Recently while checking the vmcore files, we found that in each case it appears to be a divide by zero error in the scheduler, particularly in find_busiest_group. Searching via google, we found this report at on the Red Hat site: <a href="https://bugzilla.redhat.com/show_bug.cgi?id=644903">https://bugzilla.redhat.com/show_bug.cgi?id=644903</a> [<a href="https://bugzilla.redhat.com/show_bug.cgi?id=644903" target="_blank">^</a>]<br />

This makes it look like this problem has been resolved in 2.6.32-85 but this is clearly affecting us.
