So the problem isn't something new, as it seems. You can try older kernels from my OBS repos, e.g. home:tiwai:kernel:5.11, home:tiwai:kernel:5.10, ... http://download.opensuse.org/repositories/home:/tiwai:/kernel:/5.11/standard/ http://download.opensuse.org/repositories/home:/tiwai:/kernel:/5.10/standard/ And it'd be helpful if you can find out any old working kernel (in this regard). Then we can narrow down the regression range.
