Is this a defined workflow somewhere? Is KERNEL_DEBUG_OPTIONS with this option documented somewhere? I also think the mention of devshell in the commit message is misleading, this issue happens regardless of how you enable the option. There are also other ways of enabling this than local.conf, you'd likely not want people doing that at the end of development. I'm curious on Bruce's opinion but to me this at the very least needs a commit message rewrite and I'd question whether the docs elsewhere would allow someone to discover this workflow anyway. Cheers, Richard
