I didn't know about "atacontrol". The flag "stop" doesn't exist (freeBSD
5.4) so I tried following things:
kingkong# atacontrol list
ATA channel 0:
Master: ad0 <HTS541080G9AT00/MB4IA5BJ> ATA/ATAPI revision 6
Slave: no device present
ATA channel 1:
Master: acd0 <MATSHITADVD-RAM UJ-822S/1.03> ATA/ATAPI revision 6
Slave: no device present
kingkong#
kingkong# atacontrol detach 1
kingkong# atacontrol list
ATA channel 0:
Master: ad0 <HTS541080G9AT00/MB4IA5BJ> ATA/ATAPI revision 6
Slave: no device present
ATA channel 1:
Master: no device present
Slave: no device present
kingkong#
At the same time I got following message in /var/log/messages:
Oct 26 09:41:42 kingkong kernel: acd0: WARNING - removed from
configuration
Oct 26 09:41:42 kingkong kernel: (cd0:ata1:0:0:0): lost device
Oct 26 09:41:42 kingkong kernel: (cd0:ata1:0:0:0): removing device entry
After this I removed the DVD Drive (the Power-LED of the media-slot was
still ON ?) and got following information in /var/log/messages:
Oct 26 09:44:50 kingkong kernel: stray irq15
Oct 26 09:44:50 kingkong kernel: too many stray irq 15's: not logging
anymore
I put the drive back; /var/log/messages didn't get any updates.
kingkong# atacontrol attach 1
Master: acd0 <MATSHITADVD-RAM UJ-822S/1.03> ATA/ATAPI revision 6
Slave: no device present
kingkong#
got following update in /var/log/messages:

Oct 26 09:46:20 kingkong kernel: cd0: Attempt to query device size
failed: NOT READY, Medium not present
After the whole procedure I saw the channel with "atacontrol list" and
could mount a CD without any errors. I tried the same thing with WinXP
("safe remove") to see, if the Power-LED of the media-slot is switching
off and it does.
I was wondering, if any kind of hotpluging (e.g. PCI Adapters) is
supported by freeBSD?
Regards, Thomas.
