Anyone have a more detailed explanation of this error? or a possible fix?

This is a portion of the serial console session i recored as it booted up.

"Press spacebar to enter ROM mode
Booting default method - From disk

First stage kernel: Decompressing \length erro- done"

and the LCD gets stuck on "Loading Kernal"

FYI, this is after a clean OS install (Raq3), 1st time trying to boot on its own. Turn it off and on, get same message. The same OS restore disk has successfully restored many Raq3's.
