    Subject2.6.6-rc3-mm2 oops in psmouse/serio after resuming from APM suspend-to-ram
    Date
    On a Thinkpad T41 after going into suspend via APM and then resuming, 
    the psmouse driver seems to crash after resetting itself, at which point
    the PS/2 mouse device (obviously) stops responding and I can't unload
    the psmouse module. I don't know if this is a new bug or not, as this is
    the first time I'm trying APM suspend on this laptop. The oops and the
    kernel messages before it:

    Synaptics Touchpad, model: 1
    Firmware: 5.9
    Sensor: 44
    new absolute packet format
    Touchpad has extended capability bits
    -> multifinger detection
    -> palm detection
    -> pass-through port
    printing eip:
