Hi Jürg, thanks for looking into that issue. I tested the new kernel versions. The versions you specified are without RT Kernel Patch. To be serious I never really looked on non RT patched releases on Ubuntu 24.04. Running with Kernel "6.8.0-1028-raspi #32-Ubuntu SMP PREEMPT_DYNAMIC" the described issue is not present. Nevertheless I also tested you patched version. Also no issue. But I get the exact same issue with the RT patched Kernel 6.8.0-2023. I attached the dmesg output for you.
