What exactly do you mean by wiped out?

I have a D16 with v4.6 that I regularly use suspend with and it works
absolutely fine - I can also suspend a host featuring a guest with IOMMU
graphics and then resume that host later on and continue playing video
games on the guest.

I again state my for-some-reason controversial opinion that at this rate
there will soon be no non-development boards in coreboot due to the
choices of the current leadership in determining standards.

Removing something from master is in fact removal from coreboot - one of
the reasons is as over time the older versions of software required to
compile older versions of coreboot will become un-obtainable already to
compile master critical old GPL code is only obtainable from one obscure
non-US site.
