I did remount the drive. In fact, I rebooted too. No change whatsoever. Here's the
fstab:

none /dev/pts devpts mode=0620 0 0
/dev/hda7 /home ext2 noatime,defaults 1 2
none /mnt/cdrom supermount

Firstly, I am running kernel 2.4.19-24mdk (not 2.4.19-19mdk). I have all updates
applied. I also
have supermount and scsi-emulation enabled.
I have two CD drives (hdc and hdd). The ejection problem is with /dev/cdrom1
(/dev/hdd).
Here are the steps to reproduce the problem:
1. Put a CD in the drive and close the tray by pressing the CD eject button (the
hardware
button present on the drive).
2. Press the eject button and the CD is ejected normally
3. Close the CD tray again.
4. Run a command to read /dev/cdrom1 as:
cat /dev/cdrom1
5. a) Now press the CD eject button. Nothing happens.
b) If I use "eject /dev/cdrom1", the CD is ejected fine.
6. a) If I skip step 5b and run "ls /mnt/cdrom2" (/dev/cdrom1 is mounted on
/mnt/cdrom2), then
the CD files are listed just fine.
b) After step 6a, if I press the CD eject button, it ejects normally.
This strange behavior is 100% reproducible. It seems that every time the cat command
is
used, it prevents a manual hardware ejection of the CD. After cat, using another read
command (like ls) that reads from the device, sets things right.
Further investigation revealed that if I manually umount /mnt/cdrom2 then this problem
disappears. If I manually re-mount /mnt/cdrom2, the problem reappears. Obviously,
supermount is not handling it correctly since it is related to mounting.
No error messages in dmesg or /var/log/* can be found that explains this odd behavior.
