Hi all!
Ever since I've upgraded my upboard to the new Ubuntu and kernel, I'm having troubles rebooting it.
Every time I try to reboot the upboard gets stuck and log that is printed is like so:

watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [systemd-shutdow:1]

Does anyone know what could have happen? On the Ubuntu 16.04 version everything worked just fine.

Thank you
