From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: I first tried this with cdrecord-2.0-6, but after reading the bug reports I upgraded to the latest rawhide version, but still have the problem. cdrecord -scanbus produces the following error: Cdrecord 2.0 (i686-pc-linux-gnu) Copyright (C) 1995-2002 J?rg Schilling cdrecord: Device or resource busy. Cannot open '/dev/sg0'. Cannot open SCSI driver. cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root. cdrecord: For possible transport specifiers try 'cdrecord dev=help'. Displaying /etc/hwconf reveals the following: class: CDROM bus: SCSI detached: 0 device: scd0 driver: ignore desc: " atapi 12X DVD-ROM" host: 1 id: 0 channel: 0 lun: 0 generic: sg1 - class: CDROM bus: SCSI detached: 0 device: scd1 driver: ignore desc: "Yamaha CRW2100E" host: 1 id: 1 channel: 0 lun: 0 generic: sg2 - class: TAPE bus: SCSI detached: 0 device: st driver: ignore desc: "Hp C1537A" host: 0 id: 3 channel: 0 lun: 0 generic: sg0 It seems that cdrecord is having trouble getting past the tape drive, which is a "real" SCSI device on an Adaptec controller. The cd drives are both IDE devices. This wouldn't be a big problem except that some cd-rom burning front ends try to detect the drives during startup (and crash). Problem didn't show up on RH 7.3 or 8.0. Version-Release number of selected component (if applicable): cdrecord-2.0-11.1 How reproducible: Always Steps to Reproduce: 1. run cdrecord -scanbus 2. 3. Actual Results: Produces error above. Expected Results: Should find the cdrom drives as in version 7.3 and 8.0. Additional info: Yes, removing the tape drive does make it work, but not a very good solution.
Are you logged in as root when running the cdrecord -scanbus command? I get this error also when logged in as a normal user.
Yes this was tried as root. I just tried it again as root to verify.

Created attachment 93711 [details] Screendump of up2date and cdrecord output
I just applied the patches. The problem has not changed. The best way to test this is to install a tape drive on an Adapted controller in a system running RH9. I've tried it on two now and it fails on both.
ok, I believe you :)
I too applied the updates and still have the problem with the CD hanging. Additionaly, my system seems slower in general.
then we should report these issues to the author of cdrecord, cause in the up2date version there are no RH specific patches anymore..
Maybe this should be listed as a kernel problem, and not a cdrecord problem. RH 7.3 and 8.0 worked just fine.
can you please retry with the newest rawhide versions?
ok, cannot fix this... Reopen, if the problem is still existing in newer Fedora versions.
