IMX 53 CAN0 receive stops when using IPU

We are doing a project that uses both CAN bus and the VPU and IPU for video.  Video is coming in from a UVC camera being decode from mjpeg using the VPU and then the IPU is used to do a crop, scale, rotate, colorspace change and display to fb0. When mxc_ipu_lib_task_buf_update is called to display frames we lose communication from CAN0, CAN1 continues to function normally.

 

Has anyone seen this before or have any idea what could be the cause?
