DRBD failover issue, kernal panic no init found

Pertinent details:
 * 2 node cluster
 * RHEL3
 * Kernel/OpenSSI ver: 2.4.21-27.0.2.EL_ssi_2 (install from RPM)
 * drbd version 0.7.11 (api:77)
 * SunFire X4100 2 CPU AMD Opteron hardware

drbd.conf snippet:

 on host1 {
    device     /dev/drbd/0;
    disk       /dev/sda2;
    nodenum    1;
    address    192.168.1.1:7788;
    meta-disk  /dev/sda3[0];


  on host2 {
    device    /dev/drbd/0;
    disk      /dev/sda2;
    nodenum   2;
    address   192.168.1.2:7788;
    meta-disk /dev/sda3[0];

/etc/fstab:

/dev/drbd/0 / ext3 defaults,chard,errors=remount-ro,node=1:2 0 1
/dev/sda1 /boot ext3 defaults,node=1:2 1 2
none    /dev/pts        devpts  gid=5,mode=620,node=*   0       0
none    /proc   proc    defaults,node=* 0       0
#none                    /dev/shm                tmpfs   defaults
0 0

df output:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/1/drbd/0         10080520   2329744   7238708  25% /
/dev/1/sda1             248895     61612    174433  27% /boot

The root file system is configured with DRBD, and working great. Each
node can act as an init node when booted up individually. The other node
joins the cluster, and things work great.

However, I'm having trouble with the failover.

If I 'unplug' the master node, the slave recognizes the master has gone
down, and attempts to take over. It prints DRBD timeout messages to the
console (as expected), then:

ipcnameserver ready
Kernel Panic: no init found. Cannot restart

.. and then it reboots.

I have a feeling its something fairly simple here, as DRBD itself works
fine when the nodes are booted. I'm assuming its looking for /sbin/init
to start on the slave node but can't find it? I don't know why since
DRBD itself works on either node acting as an init node when they are
booted regardless of sequence. 

Any ideas?

Thanks.
