Comment 3 for bug 1729192

I have extended the test a bit by instead of testing if a manual irqbalance shutdown is fast or slow I have tested if the system shutdown is also delayed if irqbalance is manually shutdown before a system shutdown. I have made a few system shutdowns with and without irqbalance running and in the cases where irqbalance was running the most times the system shutdown was delayed with systemd blaming the irqbalance job on the console while without irqbalance running the system shutdown was always fast.
