    Patrick,

    Thank you for taking this on.

    1) IMPROVED: S3/mem works better than ever - no resume failures encountered!

    2) WORKS AGAIN: S4/disk functionality restored, no problems seen.

    3) NEW: ACPI alarm function has new problem:

    echo > /proc/acpi/alarm often (not always) causes:

    $ cat /proc/interrupts

    4) UNCHANGED: Alarm wakeup from S3 powers up and hangs.

    5) MAJOR UNCHANGED: (ACPI routed) PCI interrupt links still stay dead
    on S3 resume as their state was lost upon powerdown of the router and
    on resume USB, Network and PCMCIA/Yenta are dead.

    I had posted a patch earlier to set all links again in ACPI prior to
    resuming devices, Russell said it was discussed at OLS, what will be
    done about it?

    6) MINOR UNCHANGED: As to the mouse, i8042 does not resume, so I
    config i8042 as a module and reload it on resume. However, current
    drivers/input/serio/Kconfig makes this impossible, which I whined
    about a few times already ;)

    config SERIO_I8042
    tristate "i8042 PC Keyboard controller" if EMBEDDED || !X86

    Maybe bug in kconfig: Even when X86 if off, can't touch i8042
    using menuconfig.

    Regards
    Michael
