I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue.
Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug: 4.0 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.0-vivid/ 4.1 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1-wily/ 4.2 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-wily/ You don't have to test every kernel, just up until the kernel that first has this bug. We can then narrow down further by testing some release candidates. Thanks in advance! ** Changed in: linux (Ubuntu) Importance: Medium => High -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
