[OOPS] XFS in large Maildir

Hi guys,
I've attached the ksymoops output from Linux 2.4.6-pre3-xfs (CVS tree from
some point). I'll try an update now, but when I try to access stuff in
~/Maildir/netfilter/cur (~7k files in it), XFS just OOPSes. The OOPS I
attached was from mutt, but it also successfully hangs ls, so I doubt it's a
mutt bug.

:) d

ksymoops 2.4.1 on i586 2.4.6-pre3-xfs.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.6-pre3-xfs/ (default)
     -m /boot/System.map-2.4.6-pre3-xfs (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
Error (regular_file): read_system_map stat /boot/System.map-2.4.6-pre3-xfs failed
Unable to handle kernel paging request at virtual address e5a8b460
