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?
