Oops in kjournald

I'm getting oops whenever I pull a big file off of an ext3 filesystem
on my large LV.  The kernel this comes from happens to have lvm 1.0.2
and posix ACL for ext2/3 patched in, but I get the crash even on 
vanilla 2.4.17.

kymoops 2.4.3 on i686 2.4.17-acl-lvm.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.17-acl-lvm/ (default)
     -m /boot/System.map (specified)

Unable to handle kernel paging request at virtual address 71bde87c
