    Btw, can you repost that one as a new email (and cc keithp too)? I
    think it got hidden in the other thread by different subject line.

    Jesse, did you take a look at that one? It was in the thread with a
    subject like "[PATCH] fix backlight brightness on intel LVDS panel
    after reopening lid".

    Search for

    When suspending intel_panel_disable_backlight() is never called,
    but intel_panel_enable_backlight() is called at resume. With the
    effect that if the brightness was ever changed after screen
    blanking, the wrong brightness gets restored at resume time.

    in your mailbox.
