Tested the daily image with the same results. Also I found an easier way to reproduce these errors.
1. At first ensure in System Settings -> Touchpad that the touchpad is not locked during typing. 2. Start moving the cursor with the touchpad and start typing during you move the cursor. After a certain number of signs you got the following error ever and ever: [ 25.224382] psmouse serio4: synaptics: Touchpad model: 1, fw: 7.2, id: 0x1c0b1, caps: 0xd047b3/0xb40000/0xa0000, board id: 71, fw id: 578367 [ 25.224399] psmouse serio4: synaptics: serio: Synaptics pass-through port at isa0060/serio4/input0 [ 33.617123] psmouse serio5: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 3/3 [ 118.758727] psmouse serio4: TouchPad at isa0060/serio4/input0 lost sync at byte 4 [ 118.764077] psmouse serio4: TouchPad at isa0060/serio4/input0 lost sync at byte 1 [ 118.785864] psmouse serio4: TouchPad at isa0060/serio4/input0 - driver resynced.
