When I press the "Fn" key and some other key on my laptop, it almost
comes to a total freeze and the error messages shown below are written
to the console over and over again. Th "Fn" key on an IBM laptop is
used to invoke functionality like switching between builtin screen and
external screen, changing lights and suspending the machine.
This behaviour is different from the one I had with 2.5.73, where the
machine did not react at all to any Fn-Key combination.
Do I have a problem with my config, is it a bug or simply
unimplemented hardware support? Any help appreciated. Please CC me on
any replies.
Thanks in advance
Jacob Hall?n

You are correct, and here is my addition to this bug report.
Some acpi events appear to lock the system.
svn revisions for pre-bug and post-bug
2.5.73 -> 11245
2.5.74 -> 11487
I will try to compile kernel revisions
(highest_good+(lowest_bad-highest_good)/2) until I
enocunter the bug.
divide and conquer it
11245 good <- 2.5.73
11366 good
11426 good
11457 good
11472 good
11479 good
11483 good
11487 good <- 2.5.74 should have been bad; reason below
After further investigation, the remaining revisions
from 11483 to 11487 (2.5.74) did not look relavant to
my situation. There was mainly an SH arch merge and
two very minimal updates to md and the bumping of the
version in the top Makefile.
At this point, I relized that I had been compiling these
kerenels without SMP, which is not what I did when I
noticed the bug. Therefor, it is an SMP-kernel-only bug.
I have a 1.9GHz Pentium 4M. My understanding is that it
does not support hyperthreading. Why would I see an SMP
bug at this point?
divide and conquer with SMP kernel on
11245 good <- 2.5.73
11306 good
11313 good
11314 good
11315 bad
11317 bad
11321 bad
11336 bad
11366 bad
11487 bad <-- 2.5.74
Therefore, the breaking patch is the changeset from svn
revion 11314 to 11315, which is reproduced below,
including the patch comment.

[PATCH] enable local APIC on P4
The current local APIC code refuses to enable the local APIC
on a P4 if the BIOS booted us with the local APIC disabled.
This patch removes this unnecessary restriction. Please apply.
Most P4 machines do boot with the local APIC enabled, but
Keith Owens reported that the P4 based Compaq Evo N800v
disables the local APIC, even though the machine actually
works if Linux enables it.
It is possible that some P4 machines with broken BIOSen
were saved by our refusal to enable the local APIC. We
can handle them via the DMI blacklist rules instead.

Conclusion:
Either there is a bug with supporting my type of APIC or my APIC
must have a bug and is disabled by the BIOS for a reason. Either
my hardware should be blacklisted or the old behavior should be
restored.
AFAIK, I have an Intel 845 chipset. I don't know what other info
is needed for blacklisting.
Thanks, Warren Turkal

In this case, the problematic 2.5.74 patch you're referring to
is NOT the culprit.
His machine is a P3 not P4, and we've _always_ force-enabled the
local APICs for all P6/K7-family processors. The 2.5.74 patch
only affects P4s.
(I'm thinking about a lapic/nolapic pair of kernel command-line
options, and possibly changing the P4 default to only enable
if lapic was on the command line. That should solve the issues
with local APIC + ACPI in broken BIOSen.)

The bug is not in the hardware but in the BIOS code.
I'm planning a patch to revert P4s to a safe default, it'll
be posted on LKML shortly.
Out of curiosity, what make & model is your laptop?
