nfs failure after woody r6 update

[Tom Brown <brown@esteem.com>]

I update our woody servers to r6 and our nfs suddenly stopped working. At 
least the timing was about right. However, I didn't see anything in the 
update that would effect nfs. 

I restarted the nfs servers: 
zan:~# /etc/init.d/nfs-kernel-server stop
Stopping NFS kernel daemon: mountd nfsd.
Unexporting directories for NFS kernel daemon...done.
zan:~# /etc/init.d/nfs-common restart
Stopping NFS common utilities: statd.
Starting NFS common utilities: statd.
zan:~# /etc/init.d/nfs-kernel-server start
Exporting directories for NFS kernel daemon...done.
Starting NFS kernel daemon: nfsd mountd.

Here is my /etc/exports:
/mirror/share 
*(rw,sync,wdelay,hide,secure,no_root_squash,no_all_squash,no_subtree_check,secure_locks,mapping=identity,anonuid=-2,anongid=-2)
/mirror/home 
*(rw,sync,wdelay,hide,secure,no_root_squash,no_all_squash,no_subtree_check,secure_locks,mapping=identity,anonuid=-2,anongid=-2)

172.16.32.9 is my workstation which automounts /mirror/share and /mirror/home. 

Here is what I see in syslog:

Any ideas?
