Hi Alex, same laptop here. I think I've talked too early... in fact, after a 3 hours turned off, I see the same issue again (80% cpu).
I've tried also the suspend mode and, after the wakeup, the first cpu goes to 100%. Another restart had caused normal cpu behaviour. About the keystrokes issue, I haven't noticed that: what keystrokes are you missing? I can't only solve the backlit problem (the backlit can't be manually (de)activated, it works just using the ambient light) and fans are always on. As an additional note, I've added samsung-tools package. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/887793 Title: Kworker constantly taking about 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/887793/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
