Not certain, but the kernel appears to be crashing before it even gets to the hard disk detection. (Based on the errors and the "function entered" being listed before the HD detection lines. That's if the listing above is accurately what's being output and isn't messed up in the translation somehow.)

Perhaps the flash memory got corrupted somehow. Try doing a RAM Test. If it passes the RAM test, try putting a fresh Hijack kernel into place and see if that fixes it.
