This problem has been noted before, perhaps only occurring with BIOS 1.57 and later.[1][2][3][4][5] Odds of a BIOS fix appear to be low: 1.57 was released over 6 years ago and although the [BIOS changelog] notes "Fixed an issue of UEFI touchpad/trackpoint/keyboard/touchscreen" in 1.58, it appears to be insufficient. Setting i8042.reset=1 or adding 33474HU to the reset list avoids the issue on my system from either warm or cold boot.
