Hi Nathan,

I took 2.6.13.4 from kernel.org and I could able to reproduce the problem.

Kernal panic appeared at the same location.

In xfs_trans_ail.c, xfs_ail_insert() causes the panic.

Based on objdump, "lip->li_ail.ail_forw->li_ail.ail_back = lip;" causes
panic because 
lip->li_ail.ail_forw is NULL

Regards,
Srikumar

Try a more recent kernel - mainline, or XFS CVS on oss.sgi.com.
