OK, I was told that the intr (or soft) option helps. Yes, it does. Thanks
for poiting this out.

Postings indicated that recent work on the NFS client/server helped both
problems. (At least my impression that it's being worked on was correct.)
I will upgrade to 2.1.132-acX (or whatever) and try.

There is something frustrating about the quality and speed of Linux
development. I.e. the quality is too high and the speed is too high, in
other words, I can implement this XXXX feature, but I bet someone else
has already done it and is just about to release his patch to Linus soon...
[From a posting of Tigran Aivazian to linux-kernel, XXXX = disk stat]
