more CD-related problems

Here is a summary of my latest CD-related problems:

o I have a CD-RW burner in /dev/hdc and a standard CD-R
in /dev/hdd.

o Although I had unexplainable problems with these a
couple of weeks ago, they now basically function
properly except for one nasty habit -- I can put a
data disk in either one, mount it, cd to it, ls, cd
back, and umount. When I press the button to eject
the disk it holds on to it.

o This is what the routine looks like from a shell.

  $ mount /cdrom
  $ cd /cdrom
  $ ls
  autorun  COPYING  preview  README  RedHat  RPM-GPG-KEY    TRANS.TBL
  $ cd
  $ umount /cdrom
  ioctl: LOOP_CLR_FD: Device or resource busy
  $ ps -ef | grep loop
  root      9402     1  0 06:59 pts/1    00:00:00 [loop0]
  lnewton   9409  8705  0 06:59 pts/1    00:00:00 grep loop
  $ eject -r
  eject: unable to eject, last error: Device or resource busy

That's it. I'll be unable to eject that disk, not as
root, not by killing processes, not by any way I know
of except by *rebooting*. (Bad computer! Very bad
computer!)

I suspect that loop process is involved somehow,
though I don't know exactly what a loop device is.

o This is what is in /etc/fstab for my CD devices:

/dev/cdrom /cdrom iso9660 noauto,user,ro,loop 0 0
/dev/burner /burner iso9660 noauto,user,ro,loop 0 0

BTW, I have my environment set *not* to automount data
disks on insertion.

Any clues what's going on here?

The never-ending battle to make *everything* on my
computer work right all at the same time goes on. I may
even accomplish it just about in time for the next
release. What fun! I'm glad I get paid for this.
