Hello
I observe a similiar behaviour here on an ASUS Laptop with a
MATSHITAUJ-831D/1.00 DVD-RW Drive. Altough only with DVD's, but not with
CD's. Installed is FreeBSD 5.3-RELEASE-p2. The only difference to the
GENERIC kernel is that I added the device atapicam to the kernel. The
failure occures with both way accessing the drive (acd0 and cd0).
If you need more output, pls. tell me.

Same happens when trying to to a 'tar ztf file.foo' (tar archive located
on DVD) - FreeBSD dies and freezes immediately.
Does it panic or hang?
The DVD has errors on it which is why you can't read it.. Obviously the OS
crashing when presented with bad media is not a good thing :)
The box hang.
The media is all right, I tried it on a FreeBSD 4.10 box and a Windows box
(equipted with the
same DVD-RW drive, running on a different hardware platform).
Writing 'clear' images to the drive results in corrupted media, either DVD
and/or CD-R/W.
