reproducable oops with 2.4.0-test9/reiserfs-3.6.17

I have a 2.4.0-test9/reiserfs-3.6.17 (as well as various other patches
which I can enumerate if you think it matters) system which is oopsing
reproducably. The sequence to reproduce is:

o make a reiserfs filesystem
o mount it
o run "find /usr -mount -depth | cpio -pvudm /mnt/reiserfs" to bulk copy
  data to it

During the cpio I get:

The "BUG" message and the oops happen at the same time.

Is there anything more I can do to help track this down?
