I have an audio app that uses the ALSA driver for the SSM2603. When I kill this app using 'kill' or just ctrl-c it, the system locks up and the watchdog fires off to reboot the system. The system accepts no input after I send the signal. I've traced it down to a change in the ALSA config. When I make the change below, the system responds normally (ie, I can keep typing in my terminal on my device after I kill the process). Any ideas?
FYI, I've attached the ALSA configs which shows that when the value is set to 'true', the system doesn't lock up.

I've moved this to the Linux Distribution for Blackfin community, as I believe it relates specifically to using the Advanced Linux Sound Architecture. Please continue the discussion here.
What's your distribution version and what your CPU? Please provide enough information.

This sounds a bit odd. Does your audio application do something special? Can you reproduce the same issue with for example aplay or arecord?
