Is this a problem you are currently seeing ? If so can you get a dump of 
 the system so we can look at that situation and diagnose the problem.

If you don't want to deal with any debugging you should remove 'options 
DDB' from your kernel config file. This is a problem that pops up from 
time to time on sudo random hardware. Normally there are several reports 
that will fly by the list before anyone will break to a debugger to give 
us a traceback.
