These (control) commands don't use DMA, so it's not a DMA issue upto this. If the card is fine, and it worked before, I would suggest a bisect. Meanwhile I'll check lo-master with my OMAP4 boards. ~Venkat -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
