[linux-lvm] linux-2.6.0 + reiser4 oops



I was testing our DBT-2 workload on linux-2.6.0 with LVM2 and reiser4
and got the following oops when I attempted to create a database with
PostgreSQL.  Let me know if I can provide any additional information:

Unable to handle kernel NULL pointer dereference at virtual address 00000000
