Can you bisect?". That's why I decided to add this to the tracking. Or am I missing something obvious here? /me looks around again and can't see anything, but that doesn't have to mean anything... Felix, btw, this guide might help you with the bisection, even if it's just for kernel compilation: https://docs.kernel.org/next/admin-guide/quickly-build-trimmed-linux.html And to indirectly reply to your mail from yesterday[1]. You might want to ignore the arch linux kernel git repo and just do a bisection between 6.1 and the latest 6.2.y kernel using upstream repos; and if I were you I'd also try 6.3 or even mainline before that, in case the issue was fixed already.
