CPU (Bios?) Lock with 2.4.12 on OB XE3

[Andy Toenz <yoschi@gmx.ch>]

Hi there,

i have a problem with my HP Omnibook XE3. The Computer locks on random times 
completely. No SysRq, no Keyboard Led's (e.g. Caps-Lock On/Off). Nothing...
Sometimes it works fine for a couple of hours, and sometimes he works 
only 45 Minutes... until complete Lock

I think it's something with VM but i'm not sure (and a trace isn't possible, 
without an oops, or the choice to SysRq the system)
memtest86 passed...
no Problems

My system has:
Kernel 2.4.12
XFree from testing
KDE from unstable
Swap: 130MB
Ram: 128 MB

... has someone the same problems ??
