aconnect occasionally causes kernel oopses

[folkert]

> In which situation?

I was testing something that listens for alsa events and for that I ran
a continuous loop that did:

while true
do
	aconnect 128:1 14:0
	aconnect -d 128:1 14:0
	aconnect -d 128:2 128:1
	aconnect 128:2 128:1
done

I ran 5 instances in parallel.

14 is midi through
128 is rtpmidi
