Kernal Panic - not syncing : Attempted to kill init!

Need some help and hoping someone here can give me a hand. I have a system that has went to a Kernal Panic and not sure what I need to do. I have a screen shot attached that shows what is going on. Any help would be great. Thanks in advance.

Holy christ, how old is your kernel?

So on reboot, the kernel can't find a filesystem on device dm-0. That's why you get the sync/init panic.

Tell us what you did right before this. Update the kernel? Change some hardware? Did you try one of the rescue kernels? Un-do whatever it is that you did, otherwise, you may have lost a hard disk :-/

The next step is to boot into rescue mode, and if possible, create an sosreport. If you have support through redhat (and you should if you're using a Red Hat product), and if it's RHEL4 or newer, you should call them. Work through the problem with a technician on the phone.
