Strange problem of /dev/cdrom disappearing under sid

[Alexis Sukrieh <sukria@sukria.net>]

Hello,

I'm experiencing a really strange issue there, with a laptop under a
fresh sid system (installed from scratch two days ago).

The laptop is an ASUS W3V, the CDROM device is a CDRW/DVD+R writer
combo.

First of all, the CDROM device works great: I can boot on the Sarge
netinst CDROM, moreover it's well seen in the BIOS.

Everything looks ok for the hardware: I can open it and when I put a CD
media inside, the device starts cycling it as expected.

Note that I used to use it for burning CDRWs and DVDs and for reading
CDROM/DVDROM media. It used to work perfcectly.

Since I had a problem with my hard disk (the partition table got
corrupted during a crash), I had to reinstall a new system.

I used the Sarge 3.1 netinst CDROM (so I booted on it), then
dist-upgraded to Sid.

By now, everything looks like I don't have any CDROM device:

- The first thing I find really weird is that dmesg does not show any
information about my CDROM device. There is simply nothing about it.

- under udev, I just don't have /dev/hdc, neither the symlink /dev/cdrom

- under hotplug, I have /dev/hdc but cannot mount any device: "not a
valid block device". Moreover, eject does not work neither: "cannot
open /dev/hdc".

- cdrecord -scanbus shows nothing.

All this is true with Debian kernels 2.6.12 and 2.6.14. I also tested a
home-made 2.6.13 kernel and experienced exactly the same.

I do have listed ide-detect, ide-cd and cdrom in my /etc/modules.

Now the very strange part:
If I boot on a 2.4.27 Debian kernel, the CDROM is seen, dmesg speaks
about it...

I'm investigating for more than 2 days now, and I would really welcome
any idea that could help me getting back the device.

Please CC me as I'm not subscribed to this list.

Regards.
