Dear,

Try to boot the system in SINGLE USER MODE.

The system is not able to find the dump
device and seems to be some problem with the
filesystem.

If it is booting in the single user mode check for the filesystem usage.

The panic this system is experiencing is:
panic(display==0xbf00,flags==0x0) all vfs_mount root failed; need drivers??

This is a panic string that covers a multitude of possible causes.

The first question would be when did this start to occur, and the next question would be what has been changed?

My normal suspicion here is that some type opf configuration change has been done that needs to update the boot area, but this has not been done using commands such as lvlnboot.
Hopefully you have a good backup of the system, just in case.
