[Bug 70467] Occationally failure to write CD-R requires reboot

[Joakim Larsson]

Public bug reported:

I burnt one ISO by right click->write to disc and it all want well and
the CD is used to install Xubuntu so I know it is ok. When I tried to
burn a second CD the drive icon never showed up on the desktop when I
inserted an empty CD-R disc. Nautilus-cd-burner informed me that it
could not find a suitable media to write the disc on but the device was
listed in the pulldown. I tried in several ways to have the drive and
media to be detected:

- pulled the firewire connector and connected it agian
- changed the CD-R disc

Lastly I rebooted and it was detected normally with same CD-R disc and i
could proceed. The error is not repeatable su I guess I had a bad Karma
for the day or something. Here is suspected lines from /var/log/syslog.
I am using a fully updated Dapper 386 installation.
