Hi and thanks for answering..
Attached the bootlog with noapic parameter passed to the kernel. It 
still freezes though. :(
What I do exactly to make it freeze is after boot:

In one console I do a ping -f to a box on my local network using the 
e100 card. (integrated on the motherboard)

In another console I copy a 2.5 GB file from my USB HDD to the IDE HDD 
in a while loop (or do a readcd from USB DVD Writer to a file on IDE HDD)

In a third one I play an MP3 using mplayer (or mpg123) also in a while [ 
1 ] loop

This guarantees me a nice freeze after at most 20 Minutes. The same 
thing runs very well for hours without SMP support compiled in.
