Created attachment 814345 [details] kernel config Since I have started using Gentoo on my Thinkpad L14 Gen 2 AMD (since kernel 5.15.41) there has been a problem concerning the keyboard whereby it randomly locks up after a period that has ranged from thirty minutes to several hours. When the keyboard locks up, it occurs while a key is being pressed, which then will repeatedly be inputted in the currently selected window until either a restart, or the lid is closed and a custom ACPI event suspends the computer, in which case after the system is resumed, the problem will disappear for another random period of time. I've tried to find the error by paying close attention to `dmesg` but there is no indication of an error in the log. It is also hard to reproduce the bug simply because of the randomness of when it will occur, and the amount of time that I must wait for it to occur. I have only seen a single comment on a Reddit post expressing similar behaviour, so I am reporting the bug here so that it may have some exposure. The input device that seems to be affected is labeled 'AT Translated Set 2 keyboard' - see below. Steps to reproduce: 1. Boot computer. 2. Use the keyboard. 3. After a long period of use, keyboard will lock up. 4. Suspend the computer or restart and repeat from step 2 ad infinitum.

Is your BIOS up to date ?
(In reply to Mike Pagano from comment #1) > Is your BIOS up to date ? I just updated it now to 1.24. No update between 1.21 and 1.24 describe anything to do with the built-in keyboard in the changelog. I will keep testing and comment if it occurs again.
I can confirm the issue is still present after a BIOS update. It has just happened to me now.

You indicate dmesg doesn't show anything, canyou attach it anyways. Also, can you attach any other relevant logs since dmesg is only logs from the kernel ring buffer.
Created attachment 814774 [details] keyboard fails around ~4630 (dmesg) timestamp 18:13:35 Added dmesg for the latest session where the bug has occurred.
I've been having the same problem with my L14 since early '21 and there does not seem to be a good solution other than closing the lid (initially I hard-reset until I discovered that suspend/resume works too). There is nothing in any logs. The problem most often happens when using e.g. cursor keys up/down in a browser; it seems as if the release of the cursor key is lost and subsequently the keyboard is flooded with an endless stream of key events. Maybe it's libinput, maybe it's just the interrupt handling of the keyboard.
I've been using the evbug module to capture the input as it comes and have attached a new dmesg log (dmesg-evbug) which contains the input up until I suspend the computer. The key that got stuck was the up arrow. As per the log, it is not the key press or key release that is being repeated, but the (type 2) key hold. For the first second of the log, I am holding the key, but then I release it, the release event is not detected or it is lost, and the input continues to be fed into the computer.

Thank-you.

The only modification I made was the removal of the keypresses after resume when I typed my password. The up arrow spam should be completely intact.

I close for now as we think we found a parameter that seemed to help. If this turns out not to be the case, please feel free to reopen.
I'm reopening this because I just experienced the issue again. I'll admit that the kernel parameter has definitely helped - it occurs much less often, so much so that the bug was beginning to occur every second hour or so, and now it has been a few days, but it is indeed still happening.

Can you try booting with these additional parameters? i8042.direct i8042.dumbkbd
So hopefully without jinxing it again ;-D I've been running with the additional i8042 parameters and since then had ZERO hiccups despite daily use, whereas I got maybe only two with the previous atkbd parameter, over a period of ~2 months. Looks like all three together do the trick!
Since it still happens and seems to affect people on lkml: https://lore.kernel.org/all/aBsmhfI45zMltjcy@shell.armlinux.org.uk/
