If you still have problem, you can disable hal from polling your cd-drive with hal-disable-polling --disable /dev/scd0 and restarting hal. Given this workaround, I'm downgrading the severity to normal. It's also still uncertain, that HAL is the actual culprit and not the kernel or the firmware of your drive.

If so, it will probably be a problem in hald-addon-storage, so you could try to attach a debugger to the running hald-addon-storage instance, to see what's going on.

Bug#423880: HAL, system hangs after inserting of audio CD
Hm, maybe you are right with your kernel presumption. It is quite possible.
Perhaps it is a bug in kded's media manager.
I did some more tests and found out that hal is not the absolute reason for
this problem.
After stopping kded's media manager and hald, restarting hald
with "hald --daemon=no --verbose=yes" i got the messages:

I get the same errors with all audio CD's i have tested (original audio CD's with and without copy protection, security backups of these CD's, and last but not least with self composed audio CD's from mp3 files burned with my or other drives). > If it's the former, I guess there is nothing, we can really do about it > besides encouraging you to not buy copy protected audio CDs ;-) > Some copy protection uses defect sectors which purposefully tries to screw > up the operating system and as a side effect can cause your computer to > lock up. Many thanks, but I know the problematic with copy protection very well. ;-) > I would also say, this is a kernel problem then and not a hal problem. > It's only triggered by hal because hal tries to access the media to find > out what contents are on the cd. I'm nearly sure this issue isn't a kernel problem. I never had such kind of problems with my drives except for my last etch update. Well, mounting my data CD's or USB drives by hand like before is possible but obsolete. You should know that these CD drives are used since Suse8.2 for all thinkable CD (incl. audio CD) formats. Killing hald-addon-storage solve the problem - in my mind the main reason for a nonexistent kernel bug, but i hope we will find a better solution. ;-) > > Cheers, > Michael Can i provide you with more informations?

If it's the former, I guess there is nothing, we can really do about it besides encouraging you to not buy copy protected audio CDs ;-) Some copy protection uses defect sectors which purposefully tries to screw up the operating system and as a side effect can cause your computer to lock up. I would also say, this is a kernel problem then and not a hal problem. It's only triggered by hal because hal tries to access the media to find out what contents are on the cd.
