Problem installing new Kernel on cpanel server: VFS: Cannot Open Root Device "Label=

[SloanPeterson]

I was running Kernel:
2.4.21-27.0.2.ELsmp

Then I tried to install Kernel 2.6.11

But it will not boot, it says:
VFS: Cannot Open Root Device "Label=/" or unknown-block(0,0) Please append a correct "root=/" boot option
Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I tried using /dev/sda1 instead of Label=/, and I have the ext3 file system built in(not as a module), I also tried increasing the ramdisk size.

How do I get it to boot? Did anyone else get those errors?

Depends which disk you have / partition on. I'm not that well versed at booting Linux interactively, but just as an idea, have you tried /dev/sda3 which is quite common? Also, what types of disk do you have, are they SCSI or SATA drives, or are they IDE and so should be using /dev/hda1, etc? There's also the outside possibility that you have a corrupt root partition which would be unfortunate.
