[linux-lvm] Kernel Oops



I have tested SGI's linux-2.4-xfs in it's 2.4.7 incarnation. Compilled 
with gcc-2.96-81 on a Dell Latitude CPt400 with an Adaptec 1460A PCMCIA 
SCSI adapter.

I can do whatever I want until I mount an LVM volume. After some time 
or immediately it will panic with a dump like this:

This also happens with 2.4.8-pre3-xfs. I'm not sure if this is a LVM 
issue, a general kernel issue or an SGi/XFS issue, but I thought I'd 
bring it up here before I talked to the XFS guys as this is directly 
related to LVM (#define LVM_RELEASE_NAME "0.9.1_beta6" - perhaps a 
known problem?)
