Description of problem:
If I try to umount a CD Nautilus tells me:
umount: /mnt/cdrom: device is busy
Some /sbin/fuser output:
USER PID ACCESS COMMAND
/mnt/cdrom/ root kernel mount /mnt/cdrom
If I log out of X and back in, I can umount it.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Right click on desktop and mount CD
2. Read something from the CD in nautilus.
3. Close nautilus and try to umount the CD
Actual Results: Can't umount the CD, device busy
Expected Results: CD should pop out of my drive
what does lsof show ?
"lsof" gives nothing, it can't find any open files on the CD or if
/mnt/cdrom is open.
Also, I had to remove "hdc=ide-scsi" from the kernel parameters in
order to access the CD at all. But maybe that's ok since ide-scsi is
deprecated in 2.6 (?).
This looks like a duplicate of bug 109687.
I only experience this when running a 2.6-test* kernel, but it seems
odd no one else has reported this, since it's easy discovered.
I've re-installed FC1, added Arjanv's 2.6.0-0.test9.1.83 kernel, and
it seems the problem has "gone away". I can't reproduce it anymore.
The bug is back again. :( Using the same configuration as before. Also
I noticed that Nautilus eats 10MB of memory usage whenever I
succesfully or unsuccessfully unmount a CD in the "Disks" dialog. I've
notified the Nautilus developers about the issue.
did this go away with the fc2 kernel ?
Yes, everything is working fine in FC2.
