Failed link with DVD drive

English Hardware
#1

I am trying to set up the DVD drive on openSUSE 12.1 KDE, and for some reason it fails to link to it (dmesg shows that it is detected, but drops the link). This is the output of dmesg | grep ata2.0:

Any idea about what is wrong?

I have noticed that there are similar reports here:

Although their DVD drive models are different. Also, I don’t seem to be able to configure whether the link is using IDE or SATA (is it possible to check that from the OS?)

It would appear that this is a problem specific to openSUSE. I just tested this on Ubuntu, and it works just fine:

This was specifically on the usual 64-bit Ubuntu Oneiric LiveCD (on a USB stick). Any ideas about what is different between the two systems?

use what works!

but, if you had rather use openSUSE (thanks)–perhaps the problem is
related to the 12.1 default boot systemD…a new system which is showing
a lot of problems (though i don’t specifically remember anyone having a
DVD problem because of it)…

if available you might try at the first green boot screen: press F5 and
select “system V” as in this image
http://dl.dropbox.com/u/10573557/12.1_Misc/12.1_F5_sysV.jpg

and see if the DVD works as expected that way…

if it does then PLEASE log the bug you found…

see here http://tinyurl.com/nzhq7j for lots of info on how to log a bug,
and how to find any of those there already raised against 12.1 and
systemd…maybe there is one already pointing to the same DVD symptom
as yours…if so, please join that bug with info specific to your
hardware so the bug can be squashed…if one like like yours does not
exist please log a new one (so that they know this new symptom)…

then, please come back here with the bug number (so other folks with DVD
problems on 12.1 with systemd can follow the bugs progress AND also log
their hardware into the bug)

and someone will tell you how to fix yours so it always boots to systemv
without you pressing F5 :wink:

and above all: Have a lot of fun!

I’m afraid the problem looks kernel related. I don’t know which version
ubuntu uses, but a but report seems appropriate.

I agree. I do not think the problem is with systemd, but with the kernel. Use
the ‘uname -r’ command to see the respective versions. If openSUSE is later than
Ubuntu, you may have found a regression. If the other way, then the bug has been
fixed, and you merely need a later kernel for oS.

#6

You’re right, the problem is not with systemd. The currently installed kernel here is 3.1.0-1.2-desktop; I’ll try updating it and see if it’s fixed then.

#7

All right, updated to 3.1.9 and this bug is indeed fixed. Thanks!
