I wonder how to get the loopback for the preempt Kernel and overall why the system switched to preempt. I am not aware that I have declared such a change. I am not sure the preempt kernel is compiled for this. Any suggestions welcome. Thank you!

Hi
Have no idea for the switch, either switch the kernel back to default, or install the preempt modules which are there in the update repository…

I found the v4l2loopback-kmp-preempt, but not via YAST install Software …
zypper install v4l2loopback-kmp-preempt

seems to work, at least no error message anymore.
