This isn't working on my ep9307 board... When the system boots I get stormed with messages: dma dma1chan0: unknown interrupt! dma dma1chan0: unknown interrupt! dma dma1chan0: unknown interrupt! dma dma1chan1: unknown interrupt! dma dma1chan1: unknown interrupt! dma dma1chan1: unknown interrupt! dma dma1chan0: unknown interrupt! dma dma1chan0: unknown interrupt! dma dma1chan1: unknown interrupt! Note, I have use_dma set for the ep93xx_spi driver and am using mmc_spi. Also note, without your patch I also get a couple messages: dma dma1chan1: got interrupt while active list is empty But, the mmc card is working fine. I haven't tracked down why I get these yet. Mika, any ideas?
