[Bug 626211] [NEW] BUG: soft lockup - CPU#3 stuck for 61s! [ksmd:54]

[Tomas Cassidy]

Public bug reported:

Hardware: Sun Fire X2200 M2
This server is only running KVM for three Ubuntu Server virtual machines.  It stopped responding today and I had to manually reboot it via the eLOM interface.  When I checked the syslog, I found the following errors:

I didn't find any of these messages in any previous syslog.  One time
during login I also received the message "System information disabled
due to load higher than 1".  This was sometime during the times of the
above BUG messages.
