[Users] kernel panic 2.6.18-164.2.1.el5.028stab066.10 drbd_connector_callback

[Aleksandar Ivanisevic]

Hi,

I'm trying to use drbd in the latest rhel5 based openvz kernel but i'm
getting the following oops when starting DRBD. I'm using drbd83
package from centos extras for userland.

Is anyone else using drbd with 2.6.18-164.2.1.el5.028stab066.10?
