So the main difference is here:

	drivers/input/serio/i8042.c: 20 -> i8042 (command) [3]
	drivers/input/serio/i8042.c: 65 <- i8042 (return) [3]
	drivers/input/serio/i8042.c: 60 -> i8042 (command) [3]
	drivers/input/serio/i8042.c: 74 -> i8042 (parameter) [3]
	drivers/input/serio/i8042.c: Interrupt 1, without any data [3]

compared to

	drivers/input/serio/i8042.c: 20 -> i8042 (command) [1]
	drivers/input/serio/i8042.c: 65 <- i8042 (return) [1]
	drivers/input/serio/i8042.c: 60 -> i8042 (command) [2]
	drivers/input/serio/i8042.c: 74 -> i8042 (parameter) [2]
	drivers/input/serio/i8042.c: d3 -> i8042 (command) [2]

So it looks like it is really affected by the polling timer removal/early 
IRQ registration.
