 Well, do other drivers do ?

 At least it didn't crash your system :)

 Hmm, I don't have much time to spend on this,
 currently. SCSI bus resan is not supported,
 and I have no way to test AMD driver changes,
 since I got no such controller card (that is,
 why I needed a BETA tester :)
 
 The driver will need changes to work with the
 new generic SCSI code (from the SCSI branch),
 I think the "scan_devices" hack should be 
 removed, then. (I didn't like it at all, but
 didn't have time and test equipment to change
 that part of the code.)
