Subject: PROBLEM: ACPI hangs when invoked from keyboard

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
