[Linux-cluster] Halt nodes in cluster with cable disconnect

Hi i'm trying to setup a centos cluster with two nodes with cman, drbd,
gfs2 and i'm using ipmi for fencing. DRBD is set up between the nodes using
a dedicated interface. So, when I unplug the drbd network cable, both nodes
power off immediatly (i tried using crossover cable and both nodes
connected to a switch, but both scenarios fail), and the logs doesn't seem
to show something useful. In a previous thread on this list, it is
recommended to deactivate ACPID daemon, even at BIOS level, but I'm still
having troubles.
If I simulate a physical disconnection with ifdown command in some node,
this node reboots with no hassle, but unpluging the cable kills both nodes.
I think the first scenario is correct, but the second one is not what I
expect.
Thanks for your help the next are my cluster.conf
