Hi,

after switching to 2.6 I noticed a strange bug which makes my NFS setup 
unusable.

Setup:
Client: 2.6.2, nfs-utils 1.0.6
Server: 2.4.20, nfs-utils 1.0.6

/etc/exports on server contains:
/          aldi(rw,sync)
("aldi" is the client)

When I try to copy files from client to server, it will result in "cp" or any 
other editor going to uninterruptable sleep when the directory is mounted 
"hard", or cp will fail because of an Input/Output error when it is mounted 
"soft".
Strangely, this only applies if the file is larger than 1332 byte (!).
A file filled with zeros of size 1332 copies nicely, one with 1333 bytes 
fails.

This is reproducable and does not occur if the client runs a 2.4 kernel.
Mount options according to /proc/mounts are 
rw,nosuid,nodev,noexec,v3,rsize=8192,wsize=8192,soft,intr,udp,lock,addr=vdr
("vdr" is the server machine)

Any suggestions?
Thanks,

Marcel
