This happened to me about a week ago under -STABLE, and again today
under -STABLE, so I tried it under -CURRENT today (in single-user
mode, to reduce variables), and was able to re-create it.
I *believe* that I had successfully inserted the drive after "atacontrol
detach 1" shortly after the atacontrol-related changes were MFCed.
This laptop is a Dell Inspiron 5000e. (In fairness, I should point out
that the laptop I was using until about 3 weeks ago was very similar,
and actually had the same manufacturer. It was, however, somewhat
different, even though the peripherals, batteries, and disk drive are
interchangeable -- and the disk drive I'm using now is the same one I
have been using since March, 2001.) I track -STABLE and -CURRENT (on
different slices) daily on the machine. (One rason I do it this way is
to be able to compare -STABLE and -CURRENT on precisely the same hardware.)
Under -STABLE (which I'm running at the moment) here is some data of
interest:

The drive in question is /dev/acd0 -- the Matsushita UJDA310L.
I booted the machine to -CURRENT, in single-user mode, then:
* fsck -p
* mount -a
* umount /common [Large file system; not needed for this experiment]
* atacontrol list
* atacontrol detach 1
* atacontrol list
> removed CD-RW drive; machine reported "stray interrupt IRQ 15"
* atacontrol list [still shows nothing cnnected to channel 1]
> re-inserted CD-RW drive [screen went blank; machine unresponsive
to all but power cycle]
I recently obtained a DVD/CD (read-only) drive (Toshiba DVD-ROM drive,
model SD-C2402), and I am able to insert it OK:

Now, the above was under -STABLE (ref. the prompts), but it was under
-STABLE that I first noticed the lockup(/panic?) from inserting the
CD-RW drive.
How may I help get this fixed? (I do have a CVS repo available that I
update (at least) daily, and I have a spare slice where I can clone
either -CURRENT or -STABLE and hack at it.)
Thanks,
david
