I just put a DFE-530TX in an AMD Duron/256MB system yesterday, which
had been working fine with a DE-530 (de4x5.o) on a 10/100 MB switched
network. I booted up the system with the new card, and noticed
similar weirdness:

NFS from the client system (Duron - 2.4.0-ac4), hangs almost
immediately when trying to contact a 2.2.18 NFS server. I get "nfs
can't get task slot" errors, and "NFS server not
responding", especially after doing a "dd if=/dev/zero
of=/home/user/nfstest bs=16k count=4096". After checking, the file
/home/user/nfstest is 8192 bytes big. The client mount is a default
NFS mount, with no rsize/wsize parameters.

I then replaced the DE-530 and tried the exact same scenario as above,
and it works fine.

The other strangeness is that while the client complains about the NFS
server having disappeared, I can ping it from the same client,
transfer files using scp, and still get to the internet fine. So the
card is still working, but never receives a response to any NFS
traffic until a reboot. Other machines on the network can NFS mount
from the server without problems as well.

Anyone have any ideas?
