I'm somewhat suspicious of this result given that that commit has been in -next rather longer than one day
The boot issue exists in sound/for-next since 2018-07-18 [1], which is shortly after this commit.
So did something change in mainline that caused this to trigger? I note that there's been the other DMA issues with these platforms and MMCI so I'm wondering if there's something going on with the DMA here.
and the board doesn't visibly have a sound card in mainline (there are some I2S controllers in there but no card to use them).
The BCM2835 has HDMI Audio from vc4_hdmi. After removing the dma-channel "audio-rx" from the DTS the RPi boots properly even with the patch above.
Any ideas to investigate the issue further?
Testing with things like the lockup detector enabled might show where it's stalled out.
