Thanks for your reply, okay, then i'd like to enable preemption. I noticed it's not in the GENERIC kernel config file. So: options PREEMPTION would suffice to enable it i guess? Any experience with preemption. noticable changes? So the problem: "PREEMPTION triggers frequent hangs" is resolved? Btw, is RELENG_5 also stable or only for early adopters? I really would like to see ule working stable in combination with preemption, but in 5.3 it won't happen. Maybe ule will be enabled later in the 5 series? Is "Fine-grained network stack locking without Giant" imported in 5.3 or is a giant lock networking stack still in 5.3? Bye, Mipam.
