Breaks nfsv4 in a rather funny way:

treogen ~ # cd /usr/portage/x
treogen x # touch bla
touch: cannot touch `bla': File exists
treogen x # mkdir bla
treogen x # touch bla/bla
touch: cannot touch `bla/bla': File exists
treogen x # ls -lad *
drwxr-xr-x 2 root root 6 Nov 14 20:03 bla
treogen x # ls -la *
total 0
drwxr-xr-x 2 root root  6 Nov 14 20:03 .
drwxr-xr-x 3 root root 16 Nov 14 20:03 ..
treogen x #

So I can create new directories, but not new files. Reading files works normal.

The client is 2.6.24-rc2-mm1, the server 2.6.22-gentoo-r9.
The fstab-line from the client:
192.168.2.4:/portage    /usr/portage            nfs4
rw,noatime,nodiratime,intr 0 0

2.6.23-mm1 as client worked, some 2.6.24-rc1-git? also.

Otherwise the new -mm worked OK for me, no errors visible in the syslog.
It even fixed the ACPI Exception from regression bug 9320.
Now the output is:

Just posting this, if someone is interested in the nv_mode_filter-output...
(UDMA/33 is correct, its only a 40-wire cable)
