I have problems with hdc. hda is mostly unused, so maybe it is DMA errors prone too but I have not seen that yet.

I can't quite figure what MW/UDMA mode is active. -- vda - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
