[Bug 1596200] Re: Ubuntu 16.04: unresponsive keyboard (15 sec) after grub

[Federico Leoni]

I've tried to boot with a keylogger loaded on rc.local and as an option on lightdm to see if the keys are captured but I got no input from the moment I leave GRUB and the kernel start to load until the infamous 15 seconds after LighDM is loaded.
 
Since the issue seems to be strongly related to i8042, I've tested some kernel options:

i8042.direct - Put keyboard port into non-translated mode
i8042.dumbkbd - Pretend that controller can only read data from keyboard and cannot control its state (Don't attempt to blink the leds)
i8042.noaux - Don't check for auxiliary (== mouse) port
i8042.noloop - Disable the AUX Loopback command while probing for the AUX port
i8042.nomux - Don't check presence of an active multiplexing controller
i8042.nopnp - Don't use ACPIPnP / PnPBIOS to discover KBD/AUX controllers
i8042.reset - Reset the controller during init and cleanup

Again without any tangible results.

I've extracted from dmesg all the information from i8042 (with
'i8042.debug' option on GRUB).

Bug description:
  I've upgraded my notebook with an SSD. All works fine and I can reach
  the login in less than 10 seconds. Problem is I can't use the internal
  keyboard (perfectly working on grub) for at least 10-15 seconds, then
  it starts to working just fine. The touchpad and capacitive buttons
  are working without issues.

  Luckily I have a second HDD on my machine and I've made some tests
  with the old mechanical drive, with this unit I can input my password
  on LightDM without any delay.

  The issue is not (only) related to Xorg or LightDM, because starting in recovery mode shown the same issue with both disks: if I use an external keyboard (a Logitech k400r in my case) I have no issue at all on both login and recovery mode. 
  Seems kdb needs some time to be up and running.

  Here's a video showing a full cycle of boots:

  And here a video of the recovery mode:
