Do you mean that the brightness buttons exhibit no problems, or
that they don't work at all ? if the latter, it's always a good
idea to look at http://acpi.sourceforge.net/dsdt/view.php
to see if there is a known problem with your model's firmware.
To use the DSDT's therein, you pretty much have to recompile
your kernel.
If it's the former, i.e. the buttons work, you may still have the bug,
but your CONFIG_PREEMPT=y turns it from a fairly reproducible bug
into an intermittent one :-O

and you're never sure if it was a coincidence, right? Sounds familiar.

Sure, here it comes:
[ ... ]

cooling mode: active
[ ... ]
==> /proc/acpi/fan/FAN1/state <==
status: off

Nothing unsual. Linux is supposed to turn on a fan when
the temperature gets too high, and you do have a fan.
Everything is still consistent with the bug I referenced earlier.
If GPE's are delayed, the fan control will be delayed.
Try echoing a "1" into /proc/acpi/thermal_zone/THZN/polling_frequency.
Keep us posted.

bug: http://bugzilla.kernel.org/show_bug.cgi?id=4124 . The symptoms

the screen brightness keys. On my laptop, the fumbled events
include starting the fan  If you also notice delays in your
screen brightness controls, keep reading.
I have a workaround, which is to keep reading files under /proc/acpi.
For example reading the battery status periodically is enough to
flush out the events. Maybe running a battery applet is enough.
Another way is to poll the temperature,
echo -n 1 > /proc/acpi/thermal_zone/THRM/polling_frequency
The symptoms are reduced, but not eliminated, if you run a preemptible
kernel (CONFIG_PREEMPT=y).

acpid runs programs of your choice when events occur. If you run it,
you'll get entries in your syslog when it sees events and doesn't
know what to do with them.
I don't think acpid will help you; the problem is occurring at a
lower level.
Your laptop may work differently than mine and it is possible that
none of the above applies. Can you run this command and post the
output?

I would disable acpi.
acpi=off on bootup or in /etc/lilo.conf on the append= line

Thanks for the tip. I went right ahead and tried that, but unfortunately this
has a bad side effect: The system is not able to assign IRQs with acpi=off - it
first suggests pci=usepirqmask which does not work, then it suggests pci=biosirq
which doesn't work either. So, I'm stuck with acpi on:-(

Yeah, that's weird. Just today I tried hitting F2 during boot and voila,
there's the BIOS setup program:-) Nothing about that on the screen. But then,
who would need that, when the computer comes pre-installed with Windows which
has a nice program for that... Something to experiment with.
Thanks

First time I boot the system, it runs fine for some time, 10min to 1h,
then it suddenly shuts down. This also happens with the AC-adapter on.
Another observation: The fan is silent.
When I boot the system again (immediately after it has shut itself
down), it starts up with the fan running. Now it runs stably with no
problems.

Sounds like overheating. There is thermal shutdown.
