[linux-lvm] kernel panic when running lvm commands

[Tobias McNulty <tobias caktusgroup com>]

I'm running a freshly installed and completely up-to-date Debian etch
system.  I just installed the "lvm2" and "lvm-common" packages.

Now I'm trying to run "pvcreate" on a physical volume, but the command
segfaults and I get a kernel panic.  See attached file or:

http://erato.caktusgroup.com/~tobias/lvm-kernel-panic.txt

I've tried this on both a regular disk (/dev/hdb) and a Linux MD device
(/dev/md1) with the same results.

Any suggestions?

Thanks,
Tobias
