Comment 2 Arjan van de Ven 2004-08-20 08:00:47 UTC
does this work when run as root ?

Comment 3 drago01 2004-08-20 08:10:48 UTC
yes it does...

Comment 4 Steven Op de beeck 2004-08-20 13:40:01 UTC
I have the same problem with kernel-2.6.8-1.524. It somehow fails to
detect writing support on regular cd burners and dvd burners. DVD
write support isn't affected though.
I tried it with kernel-2.6.7-1.494.2.2, and that works without problem.

Comment 5 Steven Op de beeck 2004-08-20 14:31:45 UTC
The above is not entirely accurate.
DVD-R(W) support is detected
DVD+R(W) support is NOT
CD write is NOT
CD(RW) is detected

I don't know if this means something. Or if it's correct, but that
just what k3b reports.

Comment 6 To Luis 2004-08-20 16:15:59 UTC
The same problem over here too: 
After installing kernel-2.6.8-1.521 , my cd burner was only recognized
as reader (without writing capabilities) under k3b (TEAC CD-R56S). 
Only as root everything was properly detected.
Since it's only a CD writer, I can't say about other burning 
possibilities mentioned earlier.

Moved back to 2.6.7, to have it working again.

Comment 7 Jeremy Sanders 2004-08-24 16:24:20 UTC
Yes - I'm seeing this with the update too. Our cdrecord is setuid
(owned by root). The drive is an LG RW/DVD GCC-4320B

Logged in as root, cdrecord works. If logged in as another user the
setuid cdrecord doesn't work. Even with the permissions of the devices
open to all, cdrecord fails.

It says

"cdrecord: Cannot init drive."

Comment 8 Adam Bowns 2004-08-24 16:34:30 UTC
Don't try to record audio cd's as root with this kernel because there
is a memory leak that will eventually crash your system.

If you need to burn audio cd's you need the following patches.



There is more info on this at the lkml at


I can confirm that these patches fix the mem leak and the audio cd's
produced are not corrupt... it doesn't fix the executing as normal
user problem though.
