It seems to have a mind of its own and always be able to make it to the Exit item in the root menu ;). Whenever this happens, psmouse logs and detects the error: psmouse.c: Mouse at isa0060/serio4/input0 lost synchronization, throwing 2 bytes away. The pointing device itself is a Synaptics touchpad. I don't use the synaptics driver because every time I've tried it (intentionally and when forced to by older development kernels) it simply rendered the touchpad inoperative. I'm running a late snapshot of 2.6.0-test11 which for all intents and purposes is the same as 2.6.0. The problem that I described happens with other versions of the 2.6.0-test series. I upgraded to this snapshot a few days ago to make sure I could reproduce the problem.
