Your kernel is currently tainted due to OOT modules, can you please boot without loading those, trigger the issue and the attache the *full* kernel log please? Additionally: is that an experienced regression from a previous running kernel? Which one? Can you as well test newer kernel, from the upper suite at least 6.12.63-1 from trixie, but additonally the ones in unstable and experimental so we get a picture on the if newer upstream versions would expose the problem as well.
