At bottom of this message are some relevant lines from DMESG. I get this
from test26.s (2.6.18) in Slackware 11.0 kernel and this drives my SATA
DVD writer (Optiard 5170A) fine as long as I stipulate irqpoll at boot
time. I've been compiling new 2.6.18 kernels to support PPP and my sound
card, but no matter what I try so far, I am not getting the new kernels
to recognize the DVD writer. Maybe someone knows how test26.s is configured
or what I should include or leave out? I'd really like to just get the
config file for test26.c and add PPP and my sound card, but maybe not
possible. Any ideas which driver(s) gave these messages and assigned my
DVD writer as hda?

If you mount Disk 1, the config file in /mnt/cdrom/kernels/test26.s is
the one used to compile it.

Simply copy that to .config in /usr/src/linux (which is a symbolic link
to /usr/src/linux-2.6.18), then you can start from the "known good"
configuration.

Everything works -- if you let it.

I can make my 2.6.18 and/or 2.6.19 config(s) available if you wish.
Email me and I'll give you the URL; they are too big to post here. I
only check the yahoo mail once a day, so be patient. The setup is a
Gigabyte MoBo, Core 2 CPU, 3 SATA HDs in (software) RAID5, Plextor
SATA DVD. The only 11.0 kernel that would allow installation was
test26.s.

NOTE: In CMOS SETUP, I changed from the default DVD access mode
(legacy IDE?) so I could temporarily install an IDE drive also; I
continue to use that setting (IHC something?). Be dead certain your
SETUP is correct.

I have _not_ installed the newer CD/DVD software versions discussed
recently in this NG - so I haven't burned anything yet. But disks
mount and read just fine.

The DVD drive is seen as sr0. I append=nousb because I don't need USB
and the boot is far faster. irqpoll is not needed. Smartd gets an IO
error when it attempts to start either the short or the long test on
the drives in the RAID array. I conclude that the 2.6 kernels are
still not mature enough. I'd go back to 2.4 in an instant if I could.

First, thank Thomas Ronayne. I will try your suggestion.

Buck,

I am curious about how your DVD gets recognized as sr0. My SATA DVD
writer gets seen (when it is seen) as ide0: hda. My SATA HDD is
recognized as sda. I have been wondering if maybe I have some left
over partitioning from when I first installed FreeBSD. That assigned
the HDD as sda (DVD was called acd0, and BSD went to sda1). Then I
installed Linux, which called its partition HDD dev/sda2 and the
CD was named hda. Not sure if this is good or bad. With test26.s, I
can read/write data and audio CDs (albeit kernel had no sound card
support, separate issue). I am curious about what gave rise to your
sr0. We both otherwise have similar machines.

For now, let me try Thomas Ronayne's advice to copy the test26.s
..config file and see what happens.

Dominic

Thanks for the ideas about copying the test26.s .config. I now see
the reason I did not find it on the Slackware CD was because I do
not automatically get ls to run with the ls -a switch in the new
installation. Previously, .* files were displayed without the -a
switch.

This worked to compile a kernel that can identify my DVD writer. However,
the system now stalls during bootup from a CD with the image.iso and I
think the reason is that I no longer get the boot: prompt in which I
can enter bootup parameters. Using test26.s, I need to boot the Slackware
disk like this:

boot: test26.s irqpoll root=/dev/sda1 noinitrd ro

I think it is the irqpoll that is the critical part. Does someone know
how to add this to the kernel I am configuring and compiling myself? I
would be happy to either get a boot prompt using my image.iso file to
fill this in manually every time I boot, or to append irqpoll to the
kernel when I compile. Anyone know how to do either of these?

man lilo.conf

look for the sections on "prompt" and "append="

Does lilo.conf have anything to do with this? I am not using a
boot loader or booting from the HDD. I am booting from a CD
onto which I have written the "image.iso" file.

This is a rather wild guess, but YES. You gotta have SOME boot loader
to get a kernel load started.

append=irqpoll in /etc/lilo.conf (before you burn the bootable image)
will take care of that as well as the ro for the root partition.

I am mystified by the noinitrd, I thought a bootable OS _must_
include an initrd...

Then the bootloader is isolinux, no? And the config file is isolinux.cfg
