Hello Andrew, Thanks for your help. The problem does not show up on every boot. I really dont know, what causes it to trigger. Nevertheless, I booted with the options you suggested. I kept executing dmesg often, and this time i was lucky to get those errors back again! So I am attaching the output of dmesg. Unfortunately, I can't see any message like ".....: returned with preemption imbalance".
