I should also note, btw, that this doesn't always happen predictably. 

One 8200 running 4.2 Beta does:

(cd0:isp3:0:4:0): READ CD RECORDED CAPACITY. CDB: 25 0 0 0 0 0 0 0 0 0 
(cd0:isp3:0:4:0): NOT READY asc:3a,0
(cd0:isp3:0:4:0): Medium not present
cd0 at isp3 bus 0 target 4 lun 0
cd0: <DEC RRD45   (C) DEC 0436> Removable CD-ROM SCSI-2 device 
isp3: 0.4 get current period 0x3e offset 0xc flags 0xd500
cd0: 4.032MB/s transfers (4.032MHz, offset 12)
cd0: Attempt to query device size failed: NOT READY, Medium not present
da0: invalid primary partition table: no magic

While another does:

(cd0:isp3:0:4:0): got CAM status 0x50
(cd0:isp3:0:4:0): fatal error, failed to attach to device
(cd0:isp3:0:4:0): lost device
(cd0:isp3:0:4:0): removing device entry



Essentially the same hardware is involved.
