Thanks a lot, Tom.  I am running RELENG6 from this morning.
6.2-STABLE FreeBSD 6.2-STABLE #279: Thu Jun 14 07:50:36 CDT 2007

I've had some really weird problems with RELENG_6 since the end of  
May.  My kernel from May 21 has fewer problems.  Actually my CURRENT  
machines are giving me no grief and I'm considering upgrading this one  
to current.

Thanks again,
