<0>Kernel panic - not syncing: Fatal exception in interrupt
The eth1 interface is used for drbd replication traffic and heartbeat
monitoring. The network card is linked to another machine with the same kernel
and the same configuration using a cross-link cable. So when one of the machine
reboots, the other machine crashes with this oops. The network card is a
Broadcom NetXtreme II BCM5708 1000Base-T (B1) PCI-X 64-bit 133MHz. The machine
is running debian unstable.
