I have ACPI disabled, system will not boot when it is enabled.
I should have been ask earlier.
That is what I have enabled.

Now, we have to see how to troubleshoot missing ACPI.
Before we start, let we check can you boot with new kernel and ACPI

To make it safe just add section to /boot/grub/menu.lst that is same as
without ACPI, that way is easy to boot in working system. Here is
example, where is skipped all that is not essential for boot:

I would skip splash=silent to see the messages, that might reveal where
it stops during the boot and what are last few messages before it

The system hangs when it is booting at:
Starting udev..._

The system then completely locks up and can only be restarted bya
complete power down.

It did the same thing when I installed Suse 10.2 64 so I ended up doing
an ACPI disabled install.

I don't need to disable ACPI when installing or using Suse 10.2 32 bit.
The exactly same problem as above is described in
and there is another
and they have links to more reports that I didn't looked at, but both
mentioned that latest kernel from
solved the problem for some installations.

Mine is Athlon 64, not Athlon 64x2, and it seems that only machines with
dual CPU are affected.

Easy way to check is to set maxcpus=0 (advice in bug #232013) boot
parameter in command line on boot screen, and if USB show up than it is
the case.

Note that kernel-default.x86_64.rpm is the link to the newest which is
where rc stands for release candidate and now it is rc6. Tomorrow can be

In bug reports you can find references to rc4, rc5 and the last mentioned
in previous article was rc4, but the link was the same so it may happen
that you downloaded some later.

One of tips mentioned in bug reports was that you should remove parameter
acpi=off with new kernel in order to see USB devices.

Note also that each change in HEAD can introduce some other problems, or
reintroduce old ones. The HEAD branch is work in progres.

Please change /boot/grub/menu.lst as suggested in previous post with but
change to new section to be similar to this:
###### Stable with acpi=off ######
title openSUSE 10.2 Stable
root (hd0,2)
kernel /boot/vmlinuz-stable root=/dev/hda3 vga=0x317 acpi=off
initrd /boot/initrd-stable

Above will allow you to set symlinks
vmlinuz-stable -> vmlinuz-
initrd-stable -> initrd-

The symlinks vmlinuz and initrd will be changed after installation of rpm
file so they can't be used for stable boot option.

If you are not comfortable playing with menu.lst, post it here and I'll
add section so that you can just copy and paste whole file. That will help
you to boot different kernels and play with them until your USB works
without affecting working configuration.

It now works perfectly! Thank You very much for the effort you have put into
solving this problem.

I downloaded the very latest kernel as per your link, installed it,
re-booted and everything works perfectly without any further effort. I was
going to edit the grub menu to enable ACPI but there is no longer any
mention of acpi=off so I'm presuming it is now on.

All USB devices are now instantly recognised when they are plugged in

Both cores are working. One of the posts in the bugzilla reports said they
had only one core working after applying the new kernel.

Kind regards,

Glad you got it fixed Tony, I ran out of ideas when the module stuff
didn't work.
