Your information is still somewhat sparse- were there no console messages? Can you build a kernel that has console debugger support and break to the console debugger to find where it's wedged? Are you running SMP? What other cards (ethernet), etc.... There's nothing to demonstrate that this is directly a SCSI problem.
