It seems that the smp-affinity value gets initialized the wrong way on
boot. On my 2 cpu opteron 240 Machine all interrupts get delivered to
cpu0. When I cat the current setting of the /proc/irq/#/smp_affinity
it shows a value of '3' . When setting it manually to ffffffffffffffff
interrupts get delivered to both cpus as it should be.
Could this be an endianess issue, as 3 would be ok, if the first two
cpus should be enabled, but not if bytes get swapped?
