Trond -
I'd seen a similar problem under 2.4.19 with your NFS-ALL patch applied. The client would lock up for periods of up to several minutes at a time without generating any traffic, then would wake up and retransmit. This would continue for a few seconds (rarely more than 30 seconds of uninterrupted IO) before another huge pause-and-retransmit cycle began.
Your patch restores client performance to sane levels. It applies cleanly against 2.4.19 with NFS-ALL. I suggest you republish NFS-ALL with this patch applied, in case other people who are stuck with 2.4.19 run into this problem.
Thanks,
