Comment 24 for bug 75753

I'm not sure this is the same bug, so I'm not reopening it but I'll just add a comment.

Until a couple of days ago (sorry, I cannot be more specific), my IDE CD-Writer was working just fine. Now, with

udev 108-0ubuntu4
linux-image-2.6.20-15-generic 2.6.20-15.25

I cannot longer use it for writing.

For example, when trying to burn an ISO with nautilus, I get an empty error message dialog (no description of the error). If I then use gnomebaker, I get the following error log:

scsidev: '/dev/hdc'
devname: '/dev/hdc'
scsibus: -2 target: -2 lun: -2
Error trying to open /dev/hdc exclusively (Device or resource busy)... retrying in 1 second.

For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

Some other output in case it can be useful:

Some other information:

On Nautilus, I get a CD-ROM 1 entry on the "Places" sidebar (I've gor 2 CD Writer units on this PC). When I click on it, I get the following message:

mount: special device /dev/scd0 does not exist

When I insert a CD, though, I get a new entry on the "Places" menu and the CD (a feisty livecd) gets mounted on

/media/Ubuntu 7.04 i386,

where I would have expected that it mounts on

/media/cdrom0

This is an up-to-date clean Feisty installation (i.e. not upgraded from Edgy).
