oops with 2.4.7-xfs during find

[Julien BLACHE <jb@jblache.org>]

Hi,

I got a kernel oops this night while cron was running a find on my
disks.

I use a 2.4.7 kernel from the XFS CVS as of 20010722 14:54 (GMT).

I don't use lvm, raid or anything, the kernel was compiled with
gcc-2.96 from Debian unstable. The chipset is a Via KT133A.

ksymoops output :
