Package: openafs-modules-dkms
Version: 1.4.12.1+dfsg-3
Severity: important
When shutting down a freshly installed openafs-client machine the
openafs module crashed. Details from the syslog are below. The
particular circumstances were as follows:
1) Client machine was freshly installed with squeeze.
Only basic packages were installed, no desktop, fileserver etc.
Afs services configured to start at boot time.
2) Some files were copied from a afs server which acts both as
dbserver and fileserver. The file server runs lenny with openafs
packages from backports.
3) Afs server was shutdown (hardware problems).
4) Afs client was shutdown without problem.
5) Afs client was started, afs server was not.
6) Afs client machine works normally.
7) Afs client machine shutdown. Afs module crashed:

The problem seems to be repeatable. After this crash I started
the afs client and tried to stop afs services with
/etc/init.d/openafs-client stop
and the machine frooze with a message on the screen wich was similar to
the one above. It was not in the logs but I photographed it and can provide
it if deemed useful.
