[lug] Unable to mount root fs on unknown-block(22, 5) {no filter}

[Rodger.Wilson at Emulex.Com]

I am in the process of installing a new 2.6.5kgdb kernel.  It has successfully created an initrd image. Which I presume is at block 22, considering my error message.  Lilo load the kernel, then loads block 22, and then cant mount the image.

Kernel panic: VFS: Unable to mount root fs on unknown-block(22,5)

Could the kernel be expecting an uncompressed ram disk?

Do all ram disks have the same filesystem?

Can I verify that my ram disk is truly at block 22?
