Kernel Panic - not syncing VFS in RHEL6.3

Hi all,

My server is running RHEL6.3, and after shutting down, I am unable to boot up the server. I did not perform any upgrades or changes to the server prior to the shut down, and this is a new server without much usage.

I got this error after the grub screen.

Code:

i8042.c: Can't read CTR while initializing i8042.

RAMDISK: incomplete write (32543 != 32768)

write error

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Pid: 1, comm: swapper Not tainted 2.6.32-279.el6.x86_64 #1

Call Trace: 

  panic

  mount_block_root

  trace_kmalloc

  mount_root

  prepare_namespace

  kernel_init

  child_rip

  kernel_rip

  child_rip

I am able to boot into Rescue mode, and I followed the instructions on this website (after changing the name of the initrd), but still get the same error.

What is wrong and what else can I try? If nothing works, I'm going to reinstall the OS.

Thank you.

Here I can guess that root= parameter is wrongly specified in init file of initrd

Thanks

How can I check the root= parameter? What should be the correct value, and how can I change it?

Can you tell us what was the last commands you gave to the server?
