But it should clear the others FIFOs too? Or is this wrong?

From the datasheet:

"Reset input FIFO (RESETF)-- When set, the FIFO pointers of all three FIFOs are reset. This bit is automatically cleared after resetting the pointers."

But only the current DMA channel was stopped.

The V4L2_PIX_FMT_YUYV mode uses only on DMA channel. So there should be no difference to RGB / raw mode.

I will going on with porting my system to 2.6.25 and then test again.

Thanks
