Hi William, How is your GPU temperature when this happens? Btw, as a more permanent temporary fix than rmmod you can blacklist it by creating the file /etc/modprobe.d/blacklist-intel_powerclamp.conf and adding the line "blacklist intel_powerclamp" to it.
As for my problem, I think it's a bit counter-intuitive that powerclamp starts to inject idle time when it's the *GPU* that is hot and using 50% of the CPU for this idle stuff almost right away is certainly excessive. It also takes a really long time after the temp has gone down for powerclamp to stop and during this time the system is very sluggish. I have to say, it seems this is not working as it should. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1389077 Title: [HP ProBook 4530s] Intel Powerclamp is Slowing CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1389077/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
