Ok, so... if the issue came back from 2007 is more or less impossible to be solved... that's sucks, also because I like this 17" Chronos.
I've also tried other boot options from here https://wiki.ubuntu.com/DebuggingACPI#Trouble_Booting with no luck: - CPU goes to 100% with "pci=noacpi" or with "acpi=noirq" or with "noapic" - CPU goes to 80% with "acpi=ht" or with "pnpacpi=off" - CPU goes to 100% and the system only sees 1 cpu (and become unusable) with "acpi=off" or with "nolapic" Also "pcie_ports=compat" not works. I don't know what else I can do ... -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
