This looks vaguely familiar. i once got something similar to this, only i was getting FAR too many DriveReady SeekComplete Error's and Uncorrectable Errors. It was pretty irritating, anyway what was even more irritating was that it was happening due to a loose IDE cable ;-) However i cannot say for sure if that's true in your case as well.
i just took the cable out and re-connected properly(while the machine was off) and it started booting just fine.
