Perhaps you should be running the linux-lowlatency kernel. apt-cache search linux-lowlatency
Since the generic kernel is used for both desktop and server (as well as virtual), I don't think it is appropriate to enable preempt. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1271742 Title: CONFIG_PREEMPT is not set. Why? Status in “linux” package in Ubuntu: Confirmed Status in “linux” source package in Trusty: Won't Fix Bug description: Since the generic kernel is for generic desktop use CONFIG_PREEMPT should be set. CONFIG_NO_HZ is already there so it seems strange to me that preempt is not especially because recommendations for desktop system usually includes building a preemptible kernel.
