And for disabling preemption: We only have performance numbers for non-preemptible kernels. While kernel preemption generally should work from a functional point of view on s390, we do not have numbers about the performance costs. Nor do we have any production systems running with kernel preemption enabled currently. Therefore let's please switch to PREEMPT_NONE which has proven to work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1543165 Title: kernel: update kernel configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1543165/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
