FWIW this affects me too. I installed pretty much exactly the same installation (Ubuntu + Kodi + Steam) on two Mac minis, two days ago.
You can compare the devices if you wish - MacMini 4,1 and 5,1 respectively. 4,1 works fine, 5,1 does not. https://en.wikipedia.org/wiki/Mac_Mini#Specifications_3 Notable differences: Intel HD 3000 video on the broken 5,1 device, NVidia GT320M on working 4,1 device. Some other things as well. Also, it seemed to coincide a few times with 'video card state changes', ie. screen saving on, etc. Could be total coincidence -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1518457 Title: kswapd0 100% CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1518457/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
