    Greetings.

    I am having a bit of an issue with psmouse and suspend/resume.
    I am using the swsusp2, which is working great... (Thanks Nigel!)

    However:

    If I compile psmouse as a module and leave it in and suspend/resume
    when the laptop comes back the mouse doesn't work at all.

    If I compile psmouse as a module and unload before suspend, and reload
    after resume, the mouse works for simple movement, but all the
    advanced synaptics features no longer work. No tap for mouse button,
    no scolling, etc.

    If I compile psmouse in everything works after a suspend/resume cycle.

    I would like to be able to compile psmouse as a module. Does anyone
    see any reason the synaptics stuff wouldn't work after a
    unload/reload?

    Before a suspend/resume:

    kernel: Synaptics Touchpad, model: 1
    kernel: Firmware: 5.9
    kernel: Sensor: 51
    kernel: new absolute packet format
    kernel: Touchpad has extended capability bits
    kernel: -> 4 multi-buttons, i.e. besides standard buttons
    kernel: -> multifinger detection
    kernel: -> palm detection
    kernel: input: SynPS/2 Synaptics TouchPad on isa0060/serio4

    Afer a unload and reload:

    kernel: Synaptics Touchpad, model: 1
    kernel: Firmware: 5.9
    kernel: Sensor: 51
    kernel: new absolute packet format
    kernel: Touchpad has extended capability bits
    kernel: -> 4 multi-buttons, i.e. besides standard buttons
    kernel: -> multifinger detection
    kernel: -> palm detection
    kernel: input: SynPS/2 Synaptics TouchPad on isa0060/serio4

    So, it all looks the same there.
    I wonder if it's not something with the input layer not reconnecting
    right on reload with what the synaptics driver in X is expecting...

    In the X log after a resume/reload:

    (II) DevInputMice: ps2EnableDataReporting: succeeded
    Synaptics DeviceOn called
    (EE) xf86OpenSerial: Cannot open device /dev/input/event2
            No such device.
    (WW) Mouse0: cannot open input device

    Any ideas?
    Happy to provde more information on versions, etc...

    thanks,

    kevin
