    Hi!

    Think again. How is kernel expected to find out partition which it
    should resume from? Try all of them?

    You did swapon before suspend, that's where you specified "which
    partition". You need to tell it what to resume from...

    Strange, it looks like you tried suspending in the middle of module
    being [un]loaded?
