[SOLVED] No cdrom.

Hi

I was trying to listen to audio cd i bought recently, but there is no /dev/sr0 or /dev/cdrom on my system (anymore). Although I clearly remember reading it a few days ago.. Some info:

[cra@pintsize 10:02:16 ~]
 $ lsmod | grep cd
cdrom                  31853  0 
uhci_hcd               19144  0

It's Acer Aspire 2920Z. I have an ARCH Linux stock kernel also installed, but the symptoms seems to be the same. I put the cd in, it beeps, starts trying to rotate (the sounds looks familiar, like they always were). Any ideas?

Checked with other cd, same thing.

That isn't the problem. The device isn't showing up so it is not just a permissions problem.

Re: [SOLVED] No cdrom.

Could it be listed as sr1 or something? try:

ls /dev/sr*

Otherwise yes, it sounds like it's not being found. If you dual-boot Windows, check that it works properly there.  Failing that, check the BIOS.  Have you made any system changes recently?

Re: [SOLVED] No cdrom.

[cra@pintsize 00:42:38 ~]
 $ ls /dev/sr*
ls: cannot access /dev/sr*: No such file or directory
[cra@pintsize 00:42:41 ~]
 $ id
uid=1000(cra) gid=100(users) groups=100(users),50(games),90(network),91(video),92(audio),93(optical)

I don't remember making any "big" changes to my system. You mean hardware changes?
Also, I don't use Windows, can't check that. BIOS bootscreen shows up my cdrom.

Re: [SOLVED] No cdrom.

I don't know what is causing this problem but the recent udev update may be to blame (start by downgrading it). It may also have been caused by the recent kernel update but that is less likely.

Re: [SOLVED] No cdrom.

...
(6/6) upgrading udev                               [#################################################] 100%
ATTENTION UDEV:
---------------
Kernel 2.6.32 or newer is now required.
OSS emulation modules are not loaded by default, add to rc.conf if needed.
Arch specific cd symlinks are now no longer created.
cd and net persistent rules will no longer be autogenerated,
see <https://wiki.archlinux.org/index.php/Udev> for details.
Errors are now logged (possibly to the console) by default.

There's no /etc/udev/rules.d/75-cd-aliases-generator.rules.optional but I don't know if it has anything to do with your problem.

Re: [SOLVED] No cdrom.

I did "yaourt -S udev-compat" and "yaourt -Syu" recently and the problem is gone by today - I can "see" my cdrom.

Thanks you guys for directions (:
