Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

I've upgrade my notebook (HP dv2700 series, model dv2910us) with an SSD and now I need to wait 15 seconds after LightDM show up before I can use the internal keyboard.On bios and on GRUB the keyboard works fine but stops working the exact moment the kernel starts to load. An USB external keyboard works fine with no delay at all (different module, I know). It's not related to the SSD because even on recovery mode I can reproduce the issue with an old mechanical disk. Here's a video showing a full cycle of boots with Ubuntu 16.04: https://youtu.be/yseDPvqWNw4 And here a video of the recovery mode where the delay is much evident: https://youtu.be/vbsD9tb-Dn8 Here is my xinput configuration: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ AlpsPS/2 ALPS GlidePoint id=11 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ HP Webcam id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)] ↳ HP WMI hotkeys id=12 [slave keyboard (3)] Keyboard on id 10. Would be nice have it working at the same time of the USB module. Tested with Ubuntu/Xubuntu 14.04, 14.10, 15.04, 15.10 and the latest 16.04. Thanks.
