The aic7xxx driver is quite stable, so even if you have a broken scanner 
or broken SCSI cabling, you should simply get some error messages. A 
completely frozen computer lets me suspect a serious problem with the 
hardware of your Linux box. I'd recommend to test another SCSI adapter 
(Adaptec are generally fine), and, if that's possible for you, to test 
the same Linux installation on a different computer.
