Hi Thomas,

I've since installed the October snapshot (sorry to change another
variable ...).  Also note that there is something weird about this
drive, that it seems to only get probed on a completely cold boot.

(all are hand transcribed)
cold boot:

# kldload atapicam
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00
cd0 at ata1 bus 0 target 0 lun 0
cd0: <HL-DT-ST RW/DVD MU10N 1.05> Removable CD-ROM SCSI-0 device
cd0: 3.3000MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Medium not present


warm boot (no acd0 found):

# kldload atapicam
[nothing]


With media present:

cold boot:

# kldload atapicam
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00
cd0: at ata1 bus 0 target 0 lun 0
cd0: <HL-DT-ST RW/DVD MU10N 1.05> Removable CD-ROM SCSI-0 device

[no panic]

warm boot:

# kldload atapicam
[nothing happens]



I don't have the media that was causing the panic here at home; I'll
try to test that tomorrow and see if the panic
is gone with the new snapshot.

Any thoughts about the drive's disappearing on warm boot
would be welcome, too ...

Thanks,
