Today's -next fails to boot on Odroid X2 and XU3 with exynos_defconfig or multi_v7_defconfig with SMP=n. It appears to get stuck in a loop probing the I2S secondary DAI for some reason:

and so on ad infinitum. Vanilla multi_v7_defconfig is fine and just displays a saingle copy of that log message. Full logs and other details here:

I don't *think* it's an audio issue as mainline seems fine and all the ASoC changes have already landed in mainline for this merge window.

Thanks for the report.

Marek spotted it as well and sent a patch
