IDE drivers not loaded at boot with powerpc

[digger vermont]

Binary package hint: initramfs-tools

I'm using an up to date installation of gutsy on a powerpc. The ide drivers
are not being loaded at boot with the 2.6.22 kernels, both powerpc and
powerpc-smp.

This is not a problem with the 2.6.20 kernel that is still installed from Feisty.

I don't know how to supply a log since the boot process stops too early.

Should the boot process detect that there are ide drives or do the drivers
need to be manually loaded?

If I boot with break=top or break=premount I can run the command
"modprobe ide-core" at the initramfs prompt.

I can see that the drivers are then loaded and the drives detected.
Exiting the initramfs shell then completes the boot process.

I "solved" the problem by adding a script,
/etc/initramfs-tools/scripts/init-top/ide_core, to load the module.
I've attached the script.

Please let me know if there is any other info I can help with.
Here's my set-up.

simple script to lod ide drivers.
/etc/initramfs-tools/scripts/init-top/ide_core

[Herbert V. Riedel (hvr)]

I had the same problem here on my last-gen g4 powerbook, I did workaround it simply by adding "ide-disk" (or alternatively "ide-core") to /etc/initramfs-tools/modules and updating the initramfs image...

[Niels Kristian Bech Jensen (nkbjensen)]

Please fix this before the release of Gutsy. It is a show-stopper for non-technical users.
