OK, I've just tested 3 times, and this issue seems to be triggered by suspend/resume, which works fine the first time, but after the first resume, the kworker CPU consumption starts and the next suspend fails (bug 1214071).
I'll update to 3.11 and check if I can reproduce it there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1213917 Title: kworker thread consuming 99.8 - 100% CPU after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1213917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
