-- Problem Description --
irqbalance is not working properly in Ubuntu 14.04.1, all the interrupts are going exclusively to one CPU instead of being spread.

# service irqbalance status
irqbalance start/running, process 832

# cat /proc/interrupts  | grep -e "CPU\|eth2"
           CPU0       CPU1       CPU2       CPU3       
 35:      71814          0          0          0      XICS 4115 Level     eth2-q0
 36:      63648          0          0          2      XICS 4116 Level     eth2-q1
 37:      60697          0          0          0      XICS 4117 Level     eth2-q2
 38:      67828          0          0          0      XICS 4118 Level     eth2-q3

Even after an apt-get upgrade / distro-upgrade that updated both kernel
and irqbalance packages, it still isn't working properly.

# uname -r
3.13.0-36-generic

# dpkg -s irqbalance | grep Version
Version: 1.0.6-2ubuntu0.14.04.1
