Yes, it is running, I also putted a heavy load with around 10000 interrupt
per second to see if it changes the number but the output is still like
this:
#cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3 CPU4 CPU5
CPU6 CPU7
98: 78484912 0 0 0 0 0
0 0 PCI-MSI eth0
106: 79396962 0 0 0 0 0
0 0 PCI-MSI eth1
After 1 Sec:
CPU0 CPU1 CPU2 CPU3 CPU4 CPU5
CPU6 CPU7
98: 78500792 0 0 0 0 0
0 0 PCI-MSI eth0
106: 79396970 0 0 0 0 0
0 0 PCI-MSI eth1
The interesting point is that the value of affinity mask changes frequently,
when I set it to FFFFFFFF it is FF for some seconds and then it changes to
other values like 02 04 08 !

Hmmm, have you checked that irqbalance is indeed running?
