Hi all

On a new install of dapper or edgy i have the same problem.

#mount /media/cdrom
mount: special device /dev/scd0 does not exist

/etc/fstab says;

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0

ls -al /media says;

lrwxrwxrwx 1 root root 6 2007-02-04 13:03 cdrom -> cdrom0 drwxr-xr-x 2
root root 4096 2007-02-04 13:03 cdrom0

The problem is that /dev/scd0 doesn't exist.

When I do lspci it tells me about the SATA controller;

0000:00:1d.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev
e2) 0000:00:1e.0 ISA bridge: Intel Corporation 82801GHM (ICH7-M DH) LPC
Interface Bridge (rev 02)
0000:00:1f.2 IDE Interface: Intel Corporation 82801GBM/GHM (ICH7
Family)Serial ATA Storage Controllers cc=IDE (Rev 02)

If I boot to LiveCD (which works fine) /dev/scd0 does exist

So, how do I go about creating /dev/scd0 ?

I reboot to the installed OS and did;

apt-get install makedev

and then ran it.

It said something about devs being managed by udev so it put devices in a
hidden subdir, looking in that dir shows me that it has created scd0 now.

So I alter fstab to point /media/cdrom0 to /dev/.static/dev/scd0 instead
and try mounting, which gives me;

#mount /media/cdrom
mount: special device /dev/scd0 is not a valid block device

aaaargh!

This is driving me nutso

Any suggestions?

I fixed it by loading the kernel with the acpi=off option.
