HI guys, I'm being bit by this too in Ubuntu 15.10. I have a System76 Lemur (2015, Skylake) and one of my cores is always at 90% or above usage, unless I plug in a USB device, in which case the problem goes away.
I tried installing kernel 4.3 from the mainline repo, but with that kernel, my system won't even boot at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488426 Title: High CPU usage of kworker/ksoftirqd To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1488426/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
