Hi guys!
I just downloaded Knoppix 7.0.4 DVD, and find that mounting NFS filing systems fails with a kernel bug.
Running a simple "mount" command for NFS results in:
[ 4722.137838] NFS: Registering the id_resolver key typeThis appears to be a bug in the kernel triggered when trying to use NFS version 4, as discussed here:
[ 4722.137929] FS-Cache: Netfs 'nfs' registered for caching
[ 4722.143743] ------------[ cut here ]------------

The work-around is to specify NFS version 3 in the mount command (or fstab), as described here:

for example:
# mount -o nfsvers=3 server:/data /data
I hope this helps somebody. It gave me a few hours of frustration.
