Before I turned off parity in scsi-select, I tried all possible combinations of cabling (my setup is motherboard connecter -> internal cable -> external connector-> external cable -> box w/2 4G cheetahs -> active terminator), I switched out both cables, the external connector, the terminator & the box w/2 cheetahs.. No combination worked on the second channel. All combinations worked on the first channel.

My message buffer isn't quite big enough, so I've captured the serial console output for you.
