Scanner stops SuSE booting (7.3)

Hi People I have an Iwill (Initio) 2935UW SCSI controller in my PC with 2 cdroms connected internally and a Umax 1220s scanner hung off the rear "D" connector. The stock SuSE kernel will hang on boot after resetting the SCSI bus and finding the 3 devices; this even happens when trying to run setup from the CDs, but once I disconnect the scanner and cold boot everything goes without a hitch. Can anyone tell me what setting I need to reconfigure in the SuSE kernel to get the box booting with my scanner connected? TIA Brian
