DM3730 ISP hangs.

Other Parts Discussed in Thread: DM3730

HW: dm3730
SW: Linux 3.9.6.

Using above mentioned software and hardware we have integrated a image sensor(8-bit parallel.) and we are able to capture the data successfully (1time only), using YAVTA application.
My data path is as below:
Camera Sensor --->VP---->CCDC---->DDR.

If I run my V4L2 application(yavta I am using) it captures specified number of frames.  After capturing defined "N" frames, application quits. after this, If I restart the application, My board hangs and it needs a reboot to become functional again.


By adding few prints, I figured out that this hangs is in spin-locks of ispqueue.c

Anybody faced such issue? any suggestions?
