Aaaah, I can see plenty of this in syslog: Oct 14 22:30:59 p5520 kernel: [ 9481.033687] CPU3: Package temperature above threshold, cpu clock throttled (total events = 5845) Oct 14 22:30:59 p5520 kernel: [ 9481.033688] CPU7: Package temperature above threshold, cpu clock throttled (total events = 5845) Oct 14 22:30:59 p5520 kernel: [ 9481.033718] CPU1: Package temperature above threshold, cpu clock throttled (total events = 5845) Oct 14 22:30:59 p5520 kernel: [ 9481.033719] CPU5: Package temperature above threshold, cpu clock throttled (total events = 5845) Oct 14 22:30:59 p5520 kernel: [ 9481.033720] CPU0: Package temperature above threshold, cpu clock throttled (total events = 5845) Oct 14 22:30:59 p5520 kernel: [ 9481.033720] CPU4: Package temperature above threshold, cpu clock throttled (total events = 5845) Oct 14 22:30:59 p5520 kernel: [ 9481.033722] CPU6: Package temperature above threshold, cpu clock throttled (total events = 5845) Oct 14 22:30:59 p5520 kernel: [ 9481.033722] CPU2: Package temperature above threshold, cpu clock throttled (total events = 5845) Oct 14 22:30:59 p5520 kernel: [ 9481.034709] CPU3: Package temperature/speed normal Oct 14 22:30:59 p5520 kernel: [ 9481.034710] CPU0: Package temperature/speed normal Oct 14 22:30:59 p5520 kernel: [ 9481.034711] CPU4: Package temperature/speed normal Oct 14 22:30:59 p5520 kernel: [ 9481.034711] CPU7: Package temperature/speed normal Oct 14 22:30:59 p5520 kernel: [ 9481.034738] CPU2: Package temperature/speed normal Oct 14 22:30:59 p5520 kernel: [ 9481.034738] CPU6: Package temperature/speed normal Oct 14 22:30:59 p5520 kernel: [ 9481.034739] CPU1: Package temperature/speed normal Oct 14 22:30:59 p5520 kernel: [ 9481.034740] CPU5: Package temperature/speed normal
So maybe it THINKS it overheats (although it does NOT) and throttles down... -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
