Description Leigh Orf 2003-02-09 17:39:19 UTC

Description of problem: Burning a CD with RedHat 8.0 consistenly
fails with scsi errors due to concurrent access to /dev/scd0 by
magicdev process


Version-Release number of selected component (if applicable):


How reproducible: Log in under runlevel 5 (X). A process called
magicdev will be spawned.


Steps to Reproduce:
1. Log in at runlevel 5 (X)
1. sudo cdrecord -audio -dao dev=0,0,0 speed=4 *.wav
2. cdrecord will begin burning and will crash. many scsi errors in /var/log/messages

Actual results:


Expected results:


Additional info: If you kill magicdev this problem goes away! Magicdev
is concurrently accessing /dev/scd0 which messes up the cd burn.

As far as I can tell anyone who tries to burn a CD using RH 8.0
with the ide-scsi module should have this problem.

I am using the default 8.0 configuration except I am using the sawfish
window manager.

Autorun has an option to watch only named devices -- under RH7.2 I used to have
it ignore my CD writer.   Now with Magicdev under 8.0 I can't find out how to
ignore the cd-writer so I just make sure I kill magicdev if I don't want to make
coffee mats.

Ideally, of course, magicdev would "know" when a CD writer is being used for
writing and not watch it until it's been finished with, but I'd settle for an
option to ignore some devices ...

You can turn off magicdev entirely from Preferences/CD and DVD.

We have some plans in the future for locking access to the CD device,
for now, on problematical hardware you'll just have to turn magicdev
off.
