Dear Alok:
	I hope I'm not talking down here, but here are my thoughts.

1: (more of an aside, than something to fix the freezing.) Try setting
wsize and rsize to 8192, as stated in the mount man page. I've found this
speeds things up.

2: I've found trying tcp/ip NFS causes the clients to hang.

3: Have you upgraded the Linux's nfs server software? I believe there has
been some activity regarding this recently, and a new server.

Just some thoughts off my head.
