Comment 1 for bug 1874763

We have a cold reboot test in checkbox that seems to be failing with this kernel. The test runs the following commands to try to trigger a cold reboot:
 rtcwake --mode no -s 120
 sleep 5
 rtcwake -m show
 sleep 5
 dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 "org.freedesktop.login1.Manager.PowerOff" boolean:true

However, the system never fully reboots. On the serial console, I just see:
...
Press enter to configure.
[ 137.402465] systemd-shutdown[1]: Failed to wait for process: Protocol error
[ 137.406163] systemd-shutdown[1]: Failed to wait for process: Protocol error

I do have the ability to remotely remove power from the device and restore it, however after doing that, I get an oops on the serial console and the system never comes up.
