Ok, thanks. I'll try to revert some patches from -rc4. But it looks
more like a side effect IMHO. Perhaps the APM initialization code
triggers one of the numerous bugs in the bios :-/

If I enable APM in the bios, the crash is somewhat different. I get
about two pages of call traces looping back every 8 pointers.

Seems like a memory corruption to me...

2.4.19-rc3-ac5 is OK, BTW.

Cheers,
Willy
