I did some test with i8042.debug param but did not get it. I will keep an eye on this issue, if I encounter the bug again I will provide the dmesg. When I keep rebooting with ctrl+alt+del I have another problem, sometimes there will be many kernel warnings about unknown key pressed like following, after which the keyboard will be unusable, I means the pressed-key changed promiscuously.
