Could you give alsa-info.sh outputs on both working and non-working kernels? This will give more detailed information. Run alsa-info.sh with --no-upload option and attach the results. thanks, Takashi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
