[coreboot] Can't sleep/power down after flashing coreboor

[799]

Hello,

I am running Coreboor on my X230 which has Windows 10 and Qubes OS
installed.
After some issues I was able to run both OSes encrypted and all devices
(WiFi/WWAN/...) are working under coreboot. (in Qubes and Windows).

Today I found out that I am unable to shutdown or put my laptop to sleep in
under Qubes/Linux.

It was working before and it is  also working under windows (currently).

Do you have any idea where to look for a root cause why Linux can't be
shutdown.
If I try it, the screen will go blank but the system stays up and running.

I tried closing the lid and also a shutdown -h now.

Regards
