I have seen similar failures with my 4.0 i386 client writing to an AIX
server, only that I didn't have to reboot. Other accesses to the same
nfs mount would hang, too, but I could kill the hanging writing process
and everything would work again. Retrying the write would hang again, so
I think this depends on the data being transferred (more likely, the
transfer size).
