I did connect a FreeBSD workstation running amd64 over wired ethernet to
NFS serverd (same nfs that was in use when the issue happened). SO to
use a reliable workstation and not other sparc clients, no doubts over
doubts :)
Stopped other clients... just not interrupt work. Serial console on the
Netra T1 to see errors, logs, hangs.

Run bonnie++ on the FreeBSD workstation on NFS mounted volume, with
small size (128MB)- Starts to run but fails when removing directories:

start 'em...done...done...done...done...done...
Create files in sequential order...done.
Stat files in sequential order...done.
Delete files in sequential order...Bonnie: drastic I/O error (rmdir):
Directory not empty
Cleaning up test directory after error.

Actually, nothing was cleaned up.. I found the directory full of tmp
files. Tried to delete it manually and it worked fine....

Run bonnie++ on internal hard disks of the Netra, both disks work.

I tried running boniee++ locally + remotely (even if it fails)... this
should have tortured things a little bit, but no failure! No warnings in
dmesg!

Maybe it was really a bad day.. and a difficult to reproduce bug...
however the fact that bonnie++ is not reliable over NFS isn't nice either.
