Hi!

In the last days I tested different pre-2.2.2 kernel with Ingos 
SMP-patches (but not with the newest one).
As you can see I got a lot of "unexpected IRQ vector" messages.
The good news: the kernel does not crash in the most cases but only sometimes.
But I also got "NMI received for unknown reason 2d" and "stuck on TLB IPI wait 
(CPU#0)". 
There is no APM support in the kernel and it's disabled in the BIOS, too.

Please have a look at the following snapshots of my /var/log/messages.
The latest messages came from the released (vanilla) 2.2.2 kernel ...
