[ACPI-sppt] M2400N problem uing acpi : keventd at 100% CPU

Hi !

I Have a M2400N an d try to configure and use acpi on.

I use mdk9.1, with a 2.4.21-3mdk 

[oli@cosinux oli]$ uname -a
Linux cosinux 2.4.21-3mdk #1 Fri Jul 4 18:04:43 CEST 2003 i686 unknown unknown GNU/Linux

I face a lot of small problems but ... now everything run just fine
... as far as I have tested it (not very much, actually).

But keventd take 100% CPU after few minutes after booting, and since
that moment my M2400N seems to emulate à 386 running windows NT :-))))

It seems that I am not alone with this case. But ... I try switching
to 2.5.75 patched ... and never succeed to compile my kernel 2.5
modules sufficiently for a installation of this kernel too be
possible. 

When I shutdown the computer  keventd crash with a messages, just when
acpi is stopped. It is the same when I stop acpi by hand
(/etc/rc.d/init.d/acpi stop)

I have seen somebody telling that keventd was buggy ... but that's not
a solution to my pb .:-))


Thanx in advance for help !
