SubjectSMP problem

Hello !

I'm having serious problems running kernel 2.4.X SMP on a dual processor
machine.

The processors are both PII at 300Mhz but different types(Deschutes and
Klamath) and different steppings respectively 2 and 4.

The machine reboots immediately after IRQ redirection table is
displayed.

With `noapic' kernel parameter(which i read should solve some problems)
i got the same behaviour.


This seems to be a problem only with 2.4 kernel since that machine
is succesfuly running on a 2.2.18 SMP kernel .

Here you have output of `lspci -vv && cat /proc/cpuinfo' on that machine:
