Looks like a broken scsi signaling.

Have you made any changes (adding/removing scsi stuff,
changing cables, terminators?)

If not, you might have a bad disk (or loose cable)

Do you use other devices then your disk on that scsi-chain?
I have seen simular stuff with defunct exbytes...

(I like to use IDE for root, then i have "for free" a bootable disk
where i might have logfiles etc).
