The message indicates that irqbalancer did not receive a hint it expected from the device driver, but on modern versions of irqbalancer, this is not likely to impact performance. with version above 14.04 Ubuntu (8.x Extreme Management Center platform) this can be workaround
Edit the following on the appliance
Edit /etc/default/irqbalance and add this line:
The file should look like this:
#Configuration for the irqbalance daemon #Should irqbalance be enabled? ENABLED="1" #Balance the IRQs only once? ONESHOT="0" OPTIONS="--hintpolicy=ignore"
Finally restart irqbalance service:
$service irqbalance restart
If the service restart does not work try rebooting machine.
