I would recommend a newer UML.  I used to see these on a very regular
basis, but haven't in a long time.  I don't know whether it was the
host or UML since both have been upgraded multiple times.  UML has had
a number of performance improvements since 2.6.18, so this may help,
and will make your life more pleasant even if it didn't have anything
to do with the soft lockups.
