Thank you in advance for your response. > Does the noselftest patch help on your box (you'd have to adjust > i8042_dmi_noselftest_table with the DMI data for your laptop)? I applied this patch to Ubuntu kernel sources v 4.2.0-19, then put X302LA model code into DMI list, then rebuilt generic kernel and reinstalled it over Ubuntu packages After rebooting with this patch, the touchpad now survives pm-suspend well. So it is effective in my case. It still does not survive reload of psmouse module, coming as .../input5 in initial load, as .../input15 on reload, and then dying off. But now I don't need this workaround so I can live without that. Not sure if any other hardware is supposed to survive psmouse module reload at all.
