So this is the relevant error. Nasty that Armbain’s image is so much older and their APT repo frozen, so it takes long for their users to recognise issues with recent build system and/or linux/u-boot sources … Since this kernel is used on many SBCs and solves a lot of issues, I’m not keen to downgrade for a single USB port of so far 2 SBCs. But I’ll do and upload a build to testing dir to at least assure it is really delated to some change between these kernel versions.
