From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; de-DE; rv:1.7) Gecko/20040803 Firefox/0.9.3 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): kernel-2.6.8-1.521 How reproducible: Always 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 Additional info: Maybe it has somthing to do with this known bug: http://bugs.kde.org/show_bug.cgi?id=87211

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. It says "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. http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.8.1/2.6.8.1-mm3/broken-out/bio_uncopy_user-mem-leak.patch http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.8.1/2.6.8.1-mm3/broken-out/bio_uncopy_user-mem-leak-fix.patch There is more info on this at the lkml at http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&c2coff=1&th=dbce4a618e91ea4&seekm=2vbef-2oe-11%40gated-at.bofh.it#link10 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.
