I collected some more information on the problem we are seeing.
Here's what I've got:
1) SuSE 10.1 (2.6.16 kernel): running ls -R, hit Control-C-- often see
an "I/O Error", for example:
/gne/home/aa/barfod.files/mac.backup/Avi's/TNFR-IgG/Mutants/mAbs:
11.15.91
/bin/ls: reading directory
/gne/home/aa/barfod.files/mac.backup/Avi's/TNFR-IgG/Mutants/mAbs/11.15.91:
Input/output error
Here's what I captured from RPC and NFS debugging. No "disconnect"
message like I saw before, but:

Jun 9 09:50:30 lablnx01 kernel: NFS: dentry_delete(mAbs/11.15.91, 8)
Note the "reply readdir: -512", is that consistent with what you guys
are saying?
Noticeably, I cannot get the error message on a host with a newer kernel.
