Tests was done with two different Skylake systems (one with ELAN i2c touchpad, and the other with Synaptics), and randomly picked AMD, IvyBridge, Haswell, and Broadwell systems.
Each of them went through 30 reboots, and see if every hardware components, especially touchpad, still work after each boot. Skylake1 (ELAN - i2c) : Passed (Failed once *1) Skylake2 (Synaptics - i2c) : Passed AMD (Cypress - PS/2) : Passed IvyBridge (Synaptics - PS/2) : Passed Haswell (Synaptics - I2C) : Passed Broadwell (ALPS - PS/2) : Passed *1 When this happns, i2c_hid failed to communicate with touchpad. Thus touchpad still worked as a PS/2 mouse. [ 11.858424] i2c_hid i2c-DLL06FD:01: hid_descr_cmd failed Touchpad switched to i2c mode after reloading i2c_hid.
