I meant resume. It hangs during random parts at the resume sequence.

I believe your suspicious makes sense. And on these lines, that patch you
attached earlier would fix that. However my initial tries of that didn't
help. I'm going to run more tests and get back to you.

I have the CONFIG_PM_DEBUG here with no_console_suspend.
