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.

Thanks for all your suggestions!

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]
