Hi Nicola Corna,
Recently I have observed some weird phenomina related to suspension on my x230 with coreboot and ME cleansed with latest me_cleaner:
Such "settings" are completely determined with how
the first boot after flash gets powered, and are
memorized across power cycles, but unrelated to where later
boot is done, nor whether
expansion
docks are used after the first boot is DONE.
I guess it may be related to the MRC cache.
