    More correctly:

    If I suspend by typing pm-suspend or echo mem >/sys/power/state, then it
    resumes just fine. If I log in to Gnome and push the suspend button,
    then it does not resume. This seems to be the case with or without your
    patch.

    -rc8 and -rc9 with the original patch 4b4f7280 resume fine no matter how
    I suspend.
