I just started developing problems with the CD-ROM drive on my Dell RH9 (2.4.20-31.9smp #1 SMP kernel) workstation and was wondering if anyone has seen seomthing similar or has any advice (I briefly trawled through the list archive but didn't find a solution). The problem is the following output from a simple "eject /mnt/cdrom/":
[cmura@chemcca35 ~]$ eject /mnt/cdrom/ eject: unable to eject, last error: Invalid argument
The drive is mounted in fstab on /dev/cdrom, which links to scsi drive /dev/scd0. The confusing issue is that this problem arose apparently randomly (i.e., I didn't screw around with anything). Also confusing is that it seems to work after the first reboot (for any user), but then seems to work sporadically for other user accounts and not at all for mine. dmesg includes ~250(!) of the following lines (is sr0 a kernel module for CDROM?):
sr0: CDROM not ready. Make sure there is a disc in the drive.
...And /var/log/messages fills-up with similar crap:
Apr 18 04:02:01 chemcca35 kernel: sr0: CDROM not ready. Make sure there is a disc in the drive.
Apr 18 04:02:32 chemcca35 last message repeated 31 times
Apr 18 04:03:33 chemcca35 last message repeated 61 times
The hardware device seems to be recognized fine ("kudzu -p")
class: CDROM bus: SCSI ... .... ...
If anyone has any hints or pointers in the right direction I'd be greatly appreciative!...
