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".
Regards,
-Romit
