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.
