I just got a framework 13 for my birthday and put arch linux on it, and I am having keyboard issues on the new linux 6.12 kernel only. I installed the 6.6 LTS kernel alongside it and the keyboard feels fine, and booting into a live USB of endeavour running 6.10 worked fine as well, but on 6.12 it feels as though the keyboard occasionally “freezes” and queues up inputs when I type too fast. I have not had this issue on any of my other devices running arch linux on the newest 6.12 kernel.

I have the same problem on Fedora 41 with the latest 6.12.10 kernel update. Everything works fine on 6.11.4 but on 6.12 the keyboard input gets buffered for ~200ms before being displayed every few seconds.

I also have this, on arch. Changing to the available LTS (6.6) feels much nicer instantly. Unfortunately I just cleared my package cache so can’t as easily go back to 6.11 to check.

I am also on Arch, kinda (Artix), but I’ve not seen this issue (yet).
It concerns me though, and I wonder if any root cause has been found (maybe by doing a bisect?), and if any newer version of the 6.12 (or even 6.13) has fixed it.

I’m almost 100% sure this is related to the AMDGPU “lag” issue in kernels 6.12+ (roughly).

I’m also stuck on -lts due to that. I noticed it more on the mouse movements, but typing in a virtual terminal has the same lag effect. Try adding amdgpu.dcdebugmask=0x10 to your kernel cmdline to see if it helps. If so it’s definitely the same issue.

For me this feels fixed on 6.13, which came out on arch yesterday

There is no single issue for this, but this thread has been posted a couple times now. Maybe you could find some more relevant info there:

Thank you! This worked for me. I added amdgpu.dcdebugmask=0x10 to my grub and the issue feels resolved on 6.13.2.
