I remember some strange case (somewhere around 2.4.18,
yes I know you are running 2.6.0 whatever) where I needed
to set the smp_affinity manually after boot, otherwise
the second cpu would not receive any interrupts on some
dual athlon system ...

echo ff >/proc/irq/xx/smp_affinity

did the trick, everything else was working as expected ...

just a weird idea, don't blame me if it actually works ;)

best,
Herbert
