Hi list,

jackd1 on my computer strangely suddenly uses 100% cpu and I find the
following 
	ALSA: seq_lock: waiting [1 left] in sound/core/seq/seq_ports.c:266
in dmesg. I can not quit it with qjackctl and had to do a hard power
reset, despite jackd1 being still able to receive and output audio
signals.

Is this error known in any way? I can't seem to reproduce this behavior.

Thanks!
P
