Using latest TrueOS on Dell Latitude E6220.
As soon as the installer display reboot and confirm, the notebook does shutdown process, end on the uptime and then hangs. You cannot change consoles or type anything.
You have to force power down by holding power button 5 seconds.
Apparently X1 carbon has same issue with reboot.
Shutdown works fine.
Every other attempt after wards results in the same issue. Complete hang.
Just to clarify, we see the same issue with vanilla FreeBSD on these platforms as well. ACPI issue I assume?
