Problems with Linux

[Adam Huffman]

I'm unable to authenticate using kauth under Linux 2.4.7-pre6.

The error message is:

kauth: failed to store AFS token

When I tried umount /afs there was a kernel Oops:

     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.7-pre6/ (default)
     -m /boot/System.map-2.4.7-pre6 (specified)
