I have some strange issues with irqbalance sometimes overwritin
smp_affinity values for banned/ignored IRQs. The issue is reproduceable
and is mitigated when I change theway how the irqbalance command line is
built. The only difference between the resulting command is that there
is only one space between the -t parameter and the first -i parameter
value.
