Hello, Sorry for disturbing. But later I find it is not actually solved. It seems to be a regression that randomly happens. Sometimes the touchpad works after starting without any bad logs, while somethime the touchpad is completely unusable. I have filed a bug on Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=203467 If any detail is needed, please don't hesitate to contact me.
