The cache is in the typical place, /usr/vice/cache, which is in /usr.
The fstab entry for the / is the following:
/dev/sda3 /usr ext4 defaults,noatime,nodiratime,nodev 0 2
I just noticed the additional options on the /usr mount, could these be
the source of the problems?
Also, this server is part of a Bright Cluster and there is an rsync from
the disk image during bootup. I can exclude the /usr/vice/cache
directory to prevent this.
Thanks for the help on this.

What filesystem is your disk cache on? This panic indicates that afs_get_dentry_from_fh is failing, which would seem to indicate a problem with our interaction with the disk cache filesystem.<BR>
