Even slower NFS mounting with 2.4.0

[Christian Ullrich <chris@chrullrich.de>]

Hello!

About three weeks ago, I complained loudly about very slow NFS mounts
involving a 2.2.17 server and a 2.2.18 client.

Today, I complain loudly about *extremely* slow NFS mounts
with the very same server and the same client now running 2.4.0.

Using 2.2.18, every mount took about 15 seconds, now, using 2.4.0,
every mount takes exactly five minutes, which is way too long.

According to syslog, the server begins and completes its operations
related to the mount in under one second, so it seems to me that
mount on the client just takes a nap in D state.
Although the messages in the client's syslog look critical to me,
once the fs is mounted, it works fine.

Syslog on client:

Jan  6 00:18:06 c kernel: portmap: server localhost not responding, timed out
Jan  6 00:19:46 c kernel: portmap: server localhost not responding, timed out
Jan  6 00:19:46 c kernel: lockd_up: makesock failed, error=-5
Jan  6 00:21:26 c kernel: portmap: server localhost not responding, timed out

I called the mount command five minutes before the final message above.

I tried NFS with and without NFSv3 code, with no change at all.

Please help me.
