this is likely not kernel bug, see here: https://answers.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+question/176273
my guess is the touchpad gets disabled by syndaemon and for some reason fails to get re-enabled. synclient/xinput being able to re-enable the mouse speaks for this, also for me the touchpad continued to work on console with gmp.
