Do you know why CPU DAI is not registered by the time snow machine driver gets probed? Did you try to debug the I2S driver? Does perhaps deferring happen due to some I2S clocks missing? DMA seems to be already initialized. The deferral loop looks suspicious, do you perhaps know what commits in v4.8 cause such changes in probing order? Did you start to use some drivers as loadable module? As far as the error log is concerned, I would just not print anything in snow_probe() when register_card() returns EPROBE_DEFER. -- Thanks, Sylwester _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
