saLoopBack application crashing

Hi all,

After applying "5633.v4l2_patches.zip" patches this problem solved. I modified saLoopBack.c file to capture video frames into file.yuv. I'm using ADV7182 decoder chip as V4L2 sub device, when I'm running saLoopBack application it is hanging in "videobuf_waiton" function, in videobuf_waiton function it is waiting for DMA interrupt. Below is the log which I got while running saLoopBack application and attached modefied saLoopBack application, Can any one tell me what is going wrong, why it is not getting DMA interrupt.
