Summary: [asr] Bad drives on asr look zero-length and panic on access

Description Jamie Gritton 2001-03-20 20:00:01 UTC 
	When a drive connected to the Adaptec SCSI RAID card goes bad (unless
	it's part of a RAID array), it reported to the system as a working
	drive, but one with a size of zero sectors.  Anay attempt to access
	the drive, such as reading the label, panics the system.

How-To-Repeat: 	Boot with a dead drive on the asr bus.

Jamie, could you please post a debugging dump from kgdb?  I, and many other people, have no idea where to start looking for this panic.
