Ok, I think I've figured it out. After a couple (5-6) reboots/shutdown-stratup without the 80% cpu problem, it seems to be related with the phc-intel kernel module (https://launchpad.net/~createsc/+archive/3beol2).
I don't remember exactly why I added it (probably 'cause I was trying to solve the backlit keyboard and the function keys issues) and I don't know the implications of removing it but the system seems to be good. I need someone else can verify the same thing on the same laptop (Samsung Chronos 7 - NP700Z7C) -- 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
