Hm. Neil, you're right. From the OP though:

      <*> SCSI CDROM support

which is CONFIG_BLK_DEV_SR which is sr_mod which provides /dev/sr*. So
he has sr_mod built into the kernel. No module to load. Should not
compile without the requires. Hm. Maybe a missing chipset-driver like
pata_atiixp as I use?

Or systemd-udev etc. is hiccupping, so the kernel (sr_mod) provides
the dev "per se" but there's no /dev/sr* device-node created, so let's
start at the "bottom" and have a look at dmesg and some stuff ...

@allan gottlieb:

- how is that drive connected?

- Please mail the outputs of

    lsmod

    lspci

    lsscsi | grep -E 'cd|process'

    hwinfo --cdrom

(the latter is from sys-apps/hwinfo) all run as root.

Oh, and please also paste the output of

    zgrep -F -e ATA -e SCSI /proc/config.gz
or
    grep  -F -e ATA -e SCSI /boot/config-`uname -r`
or
    grep  -F -e ATA -e SCSI /usr/src/linux/.config

whatever matches your kernel best ;)

And capture the output of 'dmesg' for pasting to e.g. pastebin.org[0],
or better e.g. just the output of

    dmesg | grep -Ei 'ata|sr|scd|scsi'

and/or mail the complete dmesg output just via PM to me (or Neil??) to
filter out and quote what's relevant (there might be stuff related not
captured by the 'grep -Ei'), no need to blast all that over the 'net.

-dnh

[0] has gentoo.org a "paste" service for such stuff? (I'm just lazy)
