Issue with keyboard and touchpad

Hello,

I have a strange behavior with my keyboard and touchpad on a Thinkpad 11e Lenovo.

I run a fresh install of Arch that just replaced a Debian where my keyboard and touchpad were working fine.

In the Arch install, I had no keyboard unless I added nolapic to the grub line. I also don't have any keyboard input without running nolapic currently.

I had an Arch on this laptop before and it was running fine too.

My current problem is that as long as I only use the keyboard, everything works fine, but if I start using the touchpad, the pointer moves with lag for a few seconds and then I loose all input (keyboard and touchpad). Using a USB mouse doesn't trigger any of this and works fine.

There are a few concerning lines in my journal -xb :

Jan 29 23:20:32 Serenity kernel: cherryview-pinctrl INT33FF:00: failed to get interrupt number
Jan 29 23:20:32 Serenity kernel: cherryview-pinctrl INT33FF:01: failed to get interrupt number
Jan 29 23:20:32 Serenity kernel: cherryview-pinctrl INT33FF:02: failed to get interrupt number
Jan 29 23:20:32 Serenity kernel: cherryview-pinctrl INT33FF:03: failed to get interrupt number
Jan 29 23:20:32 Serenity kernel: pwm-lpss 80862288:00: invalid resource

I failed to find anything relevant on other threads. I have seen that there used to be an issue in the kernel with cherryview but it seems to have been solved.

Any ideas?

Re: Issue with keyboard and touchpad

Tried the lts kernel?
Comparing the dmesg's of lts (if it's different), nolapic and failing kernel might tell sth.

Did you see https://bugzilla.kernel.org/show_bug.cgi?id=194945
