Since I started running the 2.4.0-test kernels a couple of months ago
I'm not able to use my scsi cdrom and cdwriter.
Today I installed 2.4.0-test11, still the same problem.
bayes:/dev# ls -l /dev/scd0
brw-rw---- 1 root cdrom 11, 0 Oct 21 04:53 /dev/scd0
bayes:/dev# mount -t iso9660 /dev/scd0 /cdrom
mount: /dev/scd0 has wrong major or minor number
bayes:/dev# mount -V
mount: mount-2.10o
Each time I want to access the cdrom or cdwriter I have to reboot w 2.2.17
where it works fine.
I've even tried with creating a generic block device
bayes:/dev# ls -l /dev/scg0
brw-r--r-- 1 root root 21, 0 Nov 23 23:41 /dev/scg0
byes:/dev# mount -t iso9660 /dev/scg0 /cdrom
mount: /dev/scg0 has wrong major or minor number
Apart from this the 2.4.0-test kernels have been running very stable
for me. My systems are dual PII on ASUS PL97-DS and P2B-DS
According to Documentation/devices.txt nothing has changed according
major numbers for these devices from 2.2 to 2.4.
I'm grateful for any hint.

My scsi adapter is adaptec 7880 on one machine and 7890 on
the other, i.e. driver is aic7xxx
This is what 'cat /proc/scsi/scsi' says when I've booted with 2.4.0-test11

And when I give the mount command:
bayes:~# mount -t iso9660 /dev/sr0 /cdrom
mount: /dev/sr0 has wrong major or minor number
And this is what 'cat /proc/scsi/scsi' says when I've booted with 2.2.17

And when I give the mount command then:
bayes:~# mount -t iso9660 /dev/sr0 /cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
I.e. the mounting works fine.
And this is the other machine, at the moment running 2.4.0-test7

bayes:/home/orre# mount -t iso9660 /dev/sr0 /cdrom
mount: /dev/sr0 has wrong major or minor number
As I said in last mail, major number= 11 and minor = 0, which is
in accordance with the documentation for both 2.2. and 2.4.
So what can this be? Can somebody that are running scsi cdrom/cdwriter
under 2.4.0-test* kernel send me a .config file so I can see if there
is any significant difference, if you don't have any other idea of
what it can be?

Thanks Doug, sometimes I'm totally blind it seems like.
Of some reason (probably mine fault...) it seems as the flag
CONFIG_BLK_DEV_SR=y
which I've had enabled as long as I can remember of some reason was
missed when I transferred the .config file from 2.2.17 to 2.4.0
