Hello, If I'm not mistaken, this is being tracked in multiple kernel issues, https://bugzilla.kernel.org/show_bug.cgi?id=218003 (latest activity) and https://bugzilla.kernel.org/show_bug.cgi?id=217873. It seems that this could be the same IRQ issue that has been affecting many new laptops. The only success I've had is by applying the kernel parameters "i8042.nopnp i8042.direct i8042.noloop i8042.dumbkbd" which makes the keyboard work but with an extreme input delay. I have also tried building my own kernel with an IRQ patch but sadly to no avail. I have the laptop Lenovo IdeaPad Slim 3 14AMN8 so if you have a different model you might have more luck than me.

Ubuntu 22.04.3 with (later upgraded to kernel 6.2.0-32-generic) was installed in rewly purchased LENOVO V15 GEN4 AMN (AMD Ryzen 5 7520u) laptop and it was noticed that keyboard, touchpad and microphone are not working. The keyboard and touchpad work fine in BIOS setup and till GRUB (command line). It was found that when external devices such as keyboard, mouse and microphone are connected through USB and 3.5 jack, respectively, these work just fine. To confirm these are not hardware problems, Microsoft Windows 11 (Home) was installed in another disk partition and observed all these working alright. Hence a bug is being reported to draw attention of the concerned team and I request them to refer this issue and do the needful at the earliest.
