From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; de-DE; rv:1.7)
Description of problem:
After updating the kernel via rawhide k3b stopped working.
It doesn't detect my dvd bruner and cd burner as burners but as normal
cdrom/dvd rom drives. (cdrecord -scnabus also shows nothing).
I am not using ide-scsi.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.boot the new kernel
2. start k3b
3. try to burn anything
Actual Results: Burners are not detected
Expected Results: Burners should be detected
Maybe it has somthing to do with this known bug:
Created attachment 102915 [details]
output of dmesg
does this work when run as root ?
yes it does...
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.
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.
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.
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.
"cdrecord: Cannot init drive."
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.
