No irq handler for vector (irq -1)

[Peter Gueckel]

Since I upgraded to kernel-3.12.8-300.fc20.x86_64 a couple of days ago (I 
have never seen this with any other Fx or kernel), I am getting this message 
appearing in the notifications applet in the systray.

It appears every time I resume the computer from suspend. I have never seen 
it from a straight start.

Why is this happening? As I said, this is a new phenomenon that never 
occurred before.
