Yes, it is an NFS exported partition.

The patches applied well to my existing 6.2-PRE source tree (I did  
not cvsup so as to minimize the changes to the system and prove that  
this fix either does or does not work for my problem.)  There was  
minimal line fuzz, but no failures.  If this works out, I'll cvsup  
and re-patch and test the latest sources.

I'm building and installing the kernel now.  Tomorrow when I'm at the  
office I'll  try the dump again as that usually causes a lockup.

Thanks for helping me solve this.
