Comment 8 for bug 296610

I found a reproducible way to cause sync errors even with the above patch applied. This may sound a bit weird, but whenever I use the RF switch at the side of the E4300 and at the same time e.g. keep tapping the touchpad, I get something like:

psmouse.c: DualPoint TouchPad at isa0060/serio1/input0 lost synchronization, throwing 4 bytes away.

And the ALPS touchpad dissappears. Switching the RF on seems to register HID devices and that apparently interferes with the touchpad/pointing stick driver. For me this has the nasty side effect that the touchpad gets enabled even though I'm trying very hard to disable it as I keep touching it accidentally while I'm typing.
