Can you do something about html emails? Quoting them doesn't work too well.

Let me try...

v4.15-rc2: suspends/resumes ok.
4ded3be: hangs on resume.

Given that between those, there was supposed "fix" for suspend, I
believe I should try reverting that one first. .. if someone can tell
me commit id, that would help.

And yes, if everything else fails, I can probably bisect.
