Bug#293481: kernel-image-2.6.8-2-686: Cannot open root device

Looks like some driver went missing from this initrd. This would be
a bug in initrd-tools (http://bugs.debian.org/initrd-tools).
Hi Thiemo
Hmm - having to learn more about Linux bootstrapping than I'd like :-).
I tried adding these lines
ide_generic
ide_disk
ata_piix
sg
sd_mod
to /etc/mkinitrd/modules as suggested by someone on the initrd-tools
bugs page, and rebuilt my initrd image. Didn't help.
I then added some debug "echos" to the linuxrc and init scripts in
/usr/share/initrd-tools and rebuilt again. Interestingly there's no
change. It doesn't even seem to get as far as running the linuxrc script
in the first place. Comparing my working 2.6.6 and 2.6.8 initrd image,
there don't seem to be too many differences, but I'll attach the output
below. I'm slightly concerned about the warning about /dev/console, and
that modprobe.conf and modprobe.d have moved around.
I also wonder if the fact that my Linux root partition (hda5) is inside
an "extended" partition (see my original report) could that be causing a
problem for the kernel?
Thanks
Nigel
