Making a IRQ SMP Affinity change permanent

I have to change the smp_affinity of a interrupt permanently. The following code needs to be executed when the server reboots: echo "1" > /proc/irq/152/smp_affinity_list echo "2" > /proc/irq/151/smp_affinity_list echo "3" > /proc/irq/150/smp_affinity_list echo "4" > /proc/irq/149/smp_affinity_list echo "5" > /proc/irq/148/smp_affinity_list echo "6" > /proc/irq/147/smp_affinity_list echo "7" > /proc/irq/146/smp_affinity_list echo "8" > /proc/irq/145/smp_affinity_list echo "9" > /proc/irq/144/smp_affinity_list echo "10" > /proc/irq/143/smp_affinity_list echo "11" > /proc/irq/142/smp_affinity_list echo "12" > /proc/irq/141/smp_affinity_list echo "13" > /proc/irq/140/smp_affinity_list echo "14" > /proc/irq/139/smp_affinity_list echo "15" > /proc/irq/138/smp_affinity_list echo "16" > /proc/irq/137/smp_affinity_list I've added these lines to the /etc/rc.local file but the changes are not applied to the system. I've also added echo "test" > /root/test which gets executed properly, so the rc.local file gets executed. The system is running Debian 6.0.
