SSM2603 ALSA config allows for a system lockup

Question asked by MarkBishop on May 21, 2012

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.
