freescale audio AIC31xx driver crash in Suspend to memory for i.MX6SL

Hi!  Friend,

 

Has anyone successfully integrated ALSA driver with 3.14.28 on i.MX6 Solo Lite?  We could try to use the codec in normal mode.  However, it would crash when I echo mem into /sys/power/state

 

The memory dump indicates the process is stopped during mutex_lock and snd_soc_suspend.  The audio codec we integrated is AIC31xx.  Could anyone share his/her experience to deal with the freescale audio codec driver problem?

 

Vincent
