> Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
It started happening after upgrading from 18.04 to 18.10. > Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.19 kernel[0]. I can do that, but so far I don't know a reliable way to trigger the system into that state. For example at the moment I did a fresh boot and performance looks ok, as well as there are no "package temperature over threshold" messages in syslog so far. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1797802 Title: Erratic behavior of intel pstate CPU frequency control To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1797802/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
