I've seen this too - will look into the cause.

Are you running the "portmap" daemon on the uClinux board?
Select it in the userspace menuconfig, under network apps.
Yes, I'm running portmap.
I found some posts in the mailing list archives... suggesting if you drive down rsize/wsize far enough it almost always fixed the problem...
I tried rsize/wsize both equal to 256 as suggested in the email and even tried it at 8. Still the same problem. I also tried plugging directly from my PC's NIC to the ML401 RJ-45 port with a crossover cable. I tested the network settings... including pings and a tftp download initiated/downloaded by uClinux - worked fine. I'd read somewhere that NFS was fragile and took that to mean it might not be very robust in the presence of an imperfect network. So I took the network out of the equation and used the brand new crossover. But it did not resolve the problem.
