Hi there,

After mounting an NFS-Volume exported from a Windows Machine
(Hummingbird-NFS Maestro Server) a simple ls of the mount point causes an
almost complete freeze of the system (ping does still work, but nothing
else).

This did work fine in 2.4.20 but does not work on 2.4.21 anymore!

Here is the debug output I produced using:

echo 3 >/proc/sys/sunrpc/rpc_debug
echo 3 >/proc/sys/sunrpc/nfs_debug
