I've reproduced the bug with Debian testing (linux-nonfree 4.9 +
libreboot stable).

Thank you, it is interesting indeed!

While chatting on #libreboot the other day, and I've been told that this
might have been fixed upstream (coreboot), but that the fix introduces
random "forced suspends" every week or so.  I'm going to try, as I
prefer my computer to shut down every week than not being able to
suspend to ram.
