Hi David, 

Thanks for the suggestions, but I can't easily duplicate the problem.  It
just happened twice during a 1.1 gig copy (2500 users home directories).
I'm just trying to decide if I should be concerned or not.  I've had a
couple other hard drive related panics in the last few weeks.  I'm hoping
that 1.2.1 will clear that up.  I'm thinking that it is more likely the
drive or scsi card is acting up :(  Do you know if a failing drive would
normally cause panics?  I would think it would just cause a lot of 'hard
error reading ...'.  

Thanks,
	Rick
