Do you have the patch link of the fix on sw_tags breakage? I am organizing patches and testing them for reposting, but still see the sw_tags breakage during boot on arm64 system. If you have the pointer about the fix, I can grab the possible unmature code change to make sw_tags mode work to finish my testing. Thanks Baoquan
