i am on karmic 2.6.31-17-generic latest kernel version and tried following things
1. adding i8042.nomux=1 as kernel boot options
2. acpi_osi=Linux as kernal boot options
3.sudo rmmod psmouse && sudo modprobe psmouse
4.installing xfree86-driver-synaptics instead of xserver-xorg-input-synaptics
  after seeing duplicates i think this bug is not usb mouse or touchpad specific
5.as a desperate measure added following to /etc/modprobe.d/options.conf
   "options psmouse resetafter=10" but this even worsens the situation

this problem pops up randomly, mostly followed by ipw2200 firmware error.
interestingly it occurs mostly at office wifi network not at all home network.
