Changes since v2: * Due to the number of devices with problems related to selftest, let's disable selftest for any laptop device * Fix condition on reset/resume calls of i8042 controller Changes since v1: * Use reset parameter, instead of adding reset_mode parameter. * Change reset parameter from bool to unsigned int.

But when this is done in Asus devices, posterior calls to detect/init functions to elantech driver fails. Skipping selftest fixes this problem. An easier step to reproduce this problem is adding i8042.reset=1 as a kernel parameter. On Asus laptops, it'll make the system to start with the touchpad already stuck, since psmouse_probe forcibly calls the selftest function. This patch was inspired by John Hiesey's change[1], but, since this problem affects a lot of models of Asus (A455LD, K401LB, K501LX, V502LX, X302LA, X450LCP, X455LAB, X455LDB, X455LF, V502LX), let's just disable self tests for any Asus laptop.

This just worked for me, and as it is a really annoying bug (that can be seen be the large number of models affected), I just wanted to check with more people about other models, if this patch break anything. > > Anyone with a Asus K53SV, G46VW, G750JX, TP500LN, X750JN, UX31 or UX32VD wants to give this patch a try ?
