Thanks! Unfortunately, I'm unable to get a serial console with both 4.7 and 4.8 (4.6 from jessie-backports gets a serial console, but not much else). After adding "earlycon" to the boot arguments, I get the log below: Booting a command list Loading Linux 4.8.0-rc5-arm64 ... Loading initial ramdisk ... Loading device tree ...
