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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1916314 Title: HP Spectre x360 14-ea0xxx Tiger Lake Keyboard does not work until ~30-60 seconds after boot Status in linux package in Ubuntu: Confirmed Bug description: On the HP Spectre x360 14-ea0xxx (Tiger Lake), the keyboard is inoperable for ~30-60 seconds after system boot.
