I revoked the patch and this certainly had effect, however I still
doubt if the result is completely correct now.
It now seems that CPU4 (this one is handling the irqs now) spends more
time than the other CPUs:

user nice system idle iowait irq softirq sum
cpu 4 0 412 8186 0 0 79 8681
cpu0 0 0 1 1074 0 0 1 1076
cpu1 0 0 2 1075 0 0 0 1077
cpu2 0 0 1 1075 0 0 0 1076
cpu3 0 0 1 1079 0 0 0 1080
cpu4 1 0 115 941 0 0 78 1135
cpu5 2 0 99 984 0 0 0 1085
cpu6 0 0 98 977 0 0 0 1075
cpu7 0 0 95 980 0 0 0 1075

Any suggestions where this small difference is coming from?
