[coreboot] x220: cannot modify nvramcui options with newest coreboot (git a96e31b)

People
I've just upgraded my corebot  BIOS.
To have ctrl <-> fn keyboard switch, I use nvramcui as secondary payload.

The problem is that when I press esc to enter menu, then choose nvramcui,
the exit operation (with f1 key) results with immediate system hang with
large number of hexadecimal digits appearing on the screen.

It didn't happen with previous version (around 2018.01)

Could you please help?

regards,
Mat
