Description of problem:
repeatable.  CD drive works without problems otherwise.
can't run cdrecord
can't run cdrecord -scanbus successfully, cdrecord reports "no such file or
directory..." see below steps to reproduce

How reproducible:

Steps to Reproduce:
[root@scotch /root]# rmmod ide-scsi
[root@scotch /root]# insmod ide-scsi
Using /lib/modules/2.4.2-2smp/kernel/drivers/scsi/ide-scsi.o
[root@scotch /root]#  cdrecord -scanbus
Cdrecord 1.9 (i686-pc-linux-gnu) Copyright (C) 1995-2000 Jvrg Schilling
cdrecord: No such file or directory. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are
[root@scotch /root]# uname -a
Linux scotch 2.4.2-2smp #1 SMP Sun Apr 8 20:21:34 EDT 2001 i686 unknown
[root@scotch /root]# 

Actual Results:  see above

Expected Results:  the scanbus out as normal

Additional info:

Comment 1 Need Real Name 2001-07-12 19:40:27 UTC
I did some checking.  The above occurs when running X.

In a console window, the cdrom and ide-cd modules are not already loaded and they can easily loaded and all required modules for cdrecord load 
correctly (except for some that don't seem to exist anymore) and cdrecord -scanbus reports the correct data about the cd writer.  However, I can't seem 
to be able to load the required modules when in an X window.  When in X it seems that the cdrom and ide-cd modules are preloaded, the rest of the 
modules needed for cdrecord don't load without errors.

Work-around: kill the x-server before using the cdrecord.

Comment 2 Need Real Name 2001-07-12 21:05:26 UTC
If ide-cd is loaded, cdrecord doesn't see the drive.  cd-ide seems to get loaded when x is started.  Once its there it doesn't unload correctly or seem to.

I now loaded the scsi modules as part of rc5.d and rc3.d:


once loaded x can (and will) startup correctly.  the drive must then (of course) be accesses as /dec/scd0

Comment 3 Mike A. Harris 2002-01-24 20:44:08 UTC
Correct.  This isn't really a bug, just a misconfiguration. In order
to do CD burning in Linux with IDE/ATAPI CD burner drives, you must
configure your CD burner to use the ide-scsi kernel module.  The
drive is then accessed like a SCSI device.
