This value should have been a frame number somewhere in the buffer, i.e., in the range 0..0x3fff. Apparently, the pointer callback doesn't correctly calculate this value. Please remove most printk()s, and add some in the pointer callback to show both the value that you get from the DMA controller, and the value that this function returns.
