           Summary: powertop reports frequent wakeups from PS/2
                    keyboard/mouse/touchpad
           Product: Power Management
           Version: 2.5
    Kernel Version: 2.6.30
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: low
          Priority: P1
         Component: Other
        AssignedTo: power-management_other at kernel-bugs.osdl.org
        ReportedBy: yann.simon.fr at gmail.com
        Regression: No


When moving the cursor (with the mouse or the touchpad) in a X session,
powertop reports frequent wakeups from PS/2 keyboard/mouse/touchpad.

For example:
Top causes for wakeups:
  60.1% (490.0) <interrupt> : PS/2 keyboard/mouse/touchpad

When stopping moving the cursor, these wakeups disappear.

This behaviour is present with older kernels too.

Is powertop reports false?
Or is moving the cursor really waking up the computer so often?
