So the machine suspends, but never comes back?

Do you need to revert both for it to work for you? Or is the revert of
fdde0ff8590b just to avoid the conflict?

I'm assuming you bisected this, and the bisect indicated e3728b50cd9b,
and then to revert it you reverted the other commit too..

Or what?
