Hey guys-
We've been seeing some occasional soft lockups on some of our Xen boxes
reporting messages like the following:

BUG: soft lockup - CPU#3 stuck for 80s! [ovs-vswitchd:4950]
BUG: soft lockup - CPU#0 stuck for 80s! [netback/0:1126]
BUG: soft lockup - CPU#2 stuck for 91462s! [tapdisk2:8473]

I'm running OVS that is slightly pre 1.2, I intend to try 1.2.2 but just
thought I'd check and see if this was a known issue or not that was fixed.

It's certainly not a known issue but I don't see anything here that
really indicates that it's related to OVS.  It's probably a more
general issue somewhere in the Xen kernel.

Ya definitely a possibility it is something else entirely, just thought I'd check.
