Hi Greg, While testing v4.20.y on Tegra I noticed that the kernel is crashing on boot if certain sound-cards are probe deferred. This issue has been fixed in the mainline by the following commit ... commit 09ac6a817bd687e7f5dac00470262efdd72f9319 Author: Curtis Malainey <cujomalainey@xxxxxxxxxxxx> Date: Thu Jan 10 16:21:04 2019 -0800 ASoC: soc-core: fix init platform memory handling I have verified that this applies cleanly and resolves the issue on v4.20.y. Please can we include for the v4.20.y stable branch? Cheers Jon -- nvpublic
