Comment 1 Jeff Johnson 1999-08-27 14:38:59 UTC 
What kernel and knfsd are you running? Could you try the latest
kernel/knfsd from Raw Hide and see if the problem is improved?
The latest packages in Raw Hide right now should be
	kernel-2.2.12-1
	knfsd-1.4.7-2

You might also attempt to mount with the "soft" option, although that
may cause other problems ...
