Moin,

Gericom M6-T,

lidl:~ # uname -a ; cat /proc/acpi/info
Linux lidl 2.4.20 #4 Sat Dec 28 00:28:55 CET 2002 i686 unknown
version: 20021212
states: S0 S1 S4 S5

I have installed http://www.elektronikschule.de/~genannt/kacpi/
and the kernel will reliable panic. (thx Parrenin ;-)

Hope that will help to find the mystic batt-oopses
<Earny>

******************************************************************************

This patch will fix that, and kacpi runs without a problem, but that
is *NOT* a correct fix, only where you can smell a bug :
