I am not ignoring the message, I simply wasn't sure how to interpret it properly :) This cable and controller somebody gave me could have been faulty perhaps. Thanks for confirming that they're apparently functioning fine. > Interrupts are not being routed correctly to the second funcion of > your SCSI controller.

That makes sense, as irq 4 is now also used for the B channel. I vainly tried to disable COM1 in the BIOS but that didn't seem to help either. Nor did disabling the sio device. So I'll send a message to -current now. Thanks for your help Justin.
