"but we probably don't need to try any harder tracking down the history of the Armbian kernel releases here in an Ubuntu bug report..."
Agreed, so the following is just out of interest... re kernel versions, sorry for the confusion, it looks like the reboot I did today moved me up another kernel release without me realising, so I was on .111 at the beginning of the day and .113 at the end. No idea what might have been there back when things were working, but as you say, it's not so important. lsb_release -a doesn't mention armbian: $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.6 LTS Release: 16.04 Codename: xenial But the login message does: ___ _ _ _ __ ___ _ _ _ / _ \ __| |_ __ ___ (_) __| | \ \/ / | | | || | | | | |/ _` | '__/ _ \| |/ _` | \ /| | | | || |_ | |_| | (_| | | | (_) | | (_| | / \| |_| |__ _| \___/ \__,_|_| \___/|_|\__,_| /_/\_\\___/ |_| Welcome to Ubuntu Xenial with Armbian Linux 4.14.133-odroidxu4 And I should probably stop spamming this bug report with irrelevant noise now. It seems like the problem is well understood, it's a shame there isn't a simpler way of choosing between the uas and usb-storage drivers, but at least it can be done.
