Ok, scratch that. I just hit the race again also with this patch applied: [ 11.815028] q6apm-dai 3000000.remoteproc:glink-edge:gpr:service@1:dais: Adding to iommu group 23 [ 11.838667] snd-sc8280xp sound: ASoC: adding FE link failed [ 11.838774] snd-sc8280xp sound: ASoC: topology: could not load header: -517 [ 11.838916] qcom-apm gprsvc:service:2:1: tplg component load failed-517 [ 11.838996] qcom-apm gprsvc:service:2:1: ASoC: error at snd_soc_component_probe on gprsvc:service:2:1: -22 [ 11.839430] snd-sc8280xp sound: ASoC: failed to instantiate card -22 [ 11.844801] snd-sc8280xp: probe of sound failed with error -22 Sorry about the noise.
