Hi, I've also been hit by this bug on two systems (both are Lemaker Bananapi). The first system upgraded the kernel via unattended-upgrades and failed to come up after reboot. I don't have a serial cable, but I did hook up the board to a HDMI display. U-Boot loads the kernel, dtb and initramfs and starts the kernel but that's the last message and nothing happens after that anymore. My first suspicion was that something went wrong during the upgrade and the reboot might have happened before everything was configured. But I also tried manual package upgrade with a second device via apt update && apt full-upgrade followed by a manual reboot. That system didn't boot either.
I recovered both systems by replacing the contents of the directories /boot/ and /lib/modules/ with those of a recent backup (taken 3 days ago). After logging into the systems again, I downgraded the package linux-image-4.9.0-8-armmp-lpae to 4.9.130-2 and rebooted again in order to make sure no other package upgrade caused the issue. Indeed, with all packages up-to-date except linux-image-4.9.0-8-armmp-lpae, the systems work just fine. So, there must be a serious regression in 4.9.144-3 at least on armmp-lpae. My amd64 systems run fine, btw, even with the latest kernel. Thanks, Timo
