Hi!

Are you using tleds utility by any chance?
Or any utility that frequently switches keyboard indicators.

I've just discovered that running tleds (for Scroll Lock as eth0
indicator) can cause such problems, on an old MSI MS-171A. It causes
such messages:

psmouse serio4: Touchpad at isa0060/serio4/input0 lost sync at byte 4

 and can sometimes block the keyboard and mouse forever (so you have
to use external USB ones to save your data and reboot).

Anyway, this could also be a hardware problem with the internal serial bus.

Cheers.
