I did some experimentation, and I can reproduce @oystein-gisnas's result that nuking that file from `/lib/udev/rules.d/` and rebooting fixes the issue.
However, removing that file and restarting udev does *not* seem to fix the issue. So I suspect the problem is not with udev, but rather with some kernel feature that udev is enabling or toggling as part of processing that file. Also, as an aside, editing that file isn't a good workaround, since upgrading udev may clobber it again. If you instead create an `/etc/udev/rules.d/40-vm-hotadd.rules` containing the edited version, that file will take precedence over the one in `/lib`, and also be robust against udev upgrades. -- 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
