执行一段时间的 project –qws (我们的UI程序)

1,发现kinteractiveup 进程状态 SW   变成 RW  图一

2,当打开播放声音的flag 时候 发现aplay 堵塞在后台,最终导致死机内核崩溃 图二

 

3,当 kinteractiveup  RW 变成 DW 直至内核崩溃。  图三

please try to disable the frequency scaling.

In menu configuration, this option is located under: CPU Power Management > CPU Frequency scaling
