Bug Description

On the HP Spectre x360 14-ea0xxx (Tiger Lake), the keyboard is inoperable for ~30-60 seconds after system boot.

Kernel logging reveals that it did not detect the keyboard during this time.

An analysis of this and a patch can be found at:

https://www.spinics.net/lists/linux-input/msg71677.html

A workaround is to add i8042.nopnp to the kernel command line

No, I haven't. The workaround of setting i8042.nopnp is satisfactory for me, and the patch creator has done a thorough write up of the problem.

My objective in filing this bug is to raise awareness that the current version of Ubuntu has this problem - on fairly major hardware from a mainstream vendor - so that other people searching the bug tracker for it can more easily find out.

Or, that it might draw the attention of Ubuntu kernel maintainers for possible inclusion as a SAUCE patch whilst waiting for upstream inclusion.

Or, getting a bit hopeful here, that someone at Canonical could get someone at HP to fix their "quirky" i8042 emulation.

In the apport-collected CurrentDmesg.txt, the keyboard is detected at:

That's sooner than it usually takes!

Looks confirmed/triaged to me. Although testing upstream patch might speed up process.

Just wanted to post a comment here so others searching online might find this workaround.

I have an HP Pavilion 14 dv0054tu laptop with an Intel Core i5 1135G7 Tiger Lake CPU and am facing this issue of the slow keyboard delay, not responding for a few seconds after booting.

The kernel parameter "i8042.nopnp" appears to be working for me, after trying several reboots.

This is on elementary OS 6.0 Odin beta based on Ubuntu 20.04 LTS with the 5.8 kernel and also on openSUSE Tumbleweed with the 5.11 kernel and Ubuntu and Ubuntu Budgie 21.04 also with the 5.11 kernel.

Wanted to pop in and mention I've encountered this same issue on several HP Spectre devices, on some of which the current workaround doesn't seem to work (as of kernel version 5.13.10). I've put together a DKMS build of the patched module for people to use until this can be upstreamed or included as a patch in various distributions.
