Are you running clvmd? I spent some time yesterday rebooting my drbd 
nodes with various startup processes enabled. If I only had cman start 
up, everything was stable. Once clvmd was started at boot time, even if 
no filesystems were actually mounted (but VGs were active) it would 
kernel panic when I reboot one of the nodes.

I am going to see what happens when I reboot with the vg exported and 
need to also look at the updates from RHEL to see if there is a 
different version of lvm2-cluster that might fix it. I have some systems 
running RHEL6.0 that have an older release of the cluster software that 
I will try to replicate.
