After a recent update (Ubuntu 18.04.4) on an Udoo Bolt, I have a problem when I shut down the computer. It seems all running processes are killed, but the computer doesn't completely shut down (fan still runs, power light still on, etc). Updates to
GRUB have not helped. I tried adding
reboot=bios to the
GRUB_CMDLINE_LINUX_DEFAULT line without any success. I have also tried
sudo poweroff from the terminal and that doesn't work either.
Any other ideas on how to solve this problem?
