STM32F30x: DMA interrupt for Channel > 1 not raised

I use a  DMA1-CH1 associated to TIM4-CH1 to feed data to GPIOC.

I use the DMA IRQ CH1 to know when Transfer Complete is done.

In this case all works as expected.

I have a problem when used another DMA channel, for instance DMA1-CH6 with TIM3-CH1 or any other combination ( see p 173 of STM32F30X reference manuel).

The problem is that no more IRQ is raised for DMA channel different of 1 ?

What could happen ?

Regards
