Description of problem:
System: Intel P4, 3.0GHz with Hyperthreading, 1024 MB RAM, standard
ps/2 swedish keyboard.

When i boot the smp kernel with acpi=on my keyboard wont work and
kudzu tries to remove it, also the following shows up in the boot logs.

ACPI: S3 and PAE do not like each other for now, S3 disabled.
i8042.c: Can't read CTR while initializing i8042.


If i the try to boot with either a non-smp kernel or with acpi=off on
the smp kernel, then the keyboard works, and the above messages don't
appear in the logs.

Version-Release number of selected component (if applicable):
2.6.7-1.478

How reproducible:
Always

Steps to Reproduce:
1. Use a PS/2 keyboard
2. Boot a smp kernel with acpi=on

Actual Results:  Keyboard isn't recognized. kudzu runs, presumably to
say that a
component has been removed (i.e. the keyboard) but as it only has a
keyboard interface that doesn't help much!)

Expected Results:  The keyboard should have worked.

Additional info:

This problem exists for me in fedora core 2 also with
kernel-smp-2.6.6-1.435.2.3, the kernels 2.6.5-1.358 and 2.6.5-1.358smp
didnt have this problem. see bug #126168
