Coming back to the explanation of how this whole thing works, it would
seem that at the point of image writing all devices are fully functional
(not just some, as I mistakenly believed). However, the processes are
supposed to be already frozen, right? Calling suspend_prepare(), which
will essentially try to freeze the processes and kernel threads, seems
like the wrong thing to do.

Did you guys mean that we should be calling
pm_notifier_call_chain(PM_SUSPEND_PREPARE) only here?
