(LR addr is kernel/notifier.c line 95 if (nr_calls)) 。Even we test another CMOS sensor(GC2035),it also cause this problem.

       we use EZSDK_05_02 kernel linux-2.6.37-psp04.04.00.01,apply 5 patchs from   http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/p/186865/675884.aspx and also modify maxOutHeight/maxOutWidth  configs as flow:

#if 0
out_stream_info->maxOutHeight = VPS_CAPT_MAX_OUT_HEIGHT_UNLIMITED;
out_stream_info->maxOutWidth = VPS_CAPT_MAX_OUT_WIDTH_UNLIMITED;
#else
//width zeng
if(inst->buf_obj.fmt.fmt.pix.width<=352)
out_stream_info->maxOutWidth = VPS_CAPT_MAX_OUT_WIDTH_352_PIXELS;
else if(inst->buf_obj.fmt.fmt.pix.width<=768)
out_stream_info->maxOutWidth = VPS_CAPT_MAX_OUT_WIDTH_768_PIXELS;
else if(inst->buf_obj.fmt.fmt.pix.width<=1280)
out_stream_info->maxOutWidth = VPS_CAPT_MAX_OUT_WIDTH_1280_PIXELS;

can somebody help solve this problem or give me some advice? thanks!
