   After two weeks of uneventful uptime with -pre6aa1 the system hung 
with no symptoms, no messages, no way in.  XFS filesystems recovered 
themselves on reboot with no apparent problems.  About twelve hours 
later got the appended oops, in the early AM.  I suspect it may have 
been triggered by the system backup, which is now stuck in D state. 
Otherwise the system is running normally except loadavg is high (6-7) 
even though there is little CPU and IO usage.
