[Bug 1460399] Re: ivybridge system gets completely unusable after upgrade to vivid thanks to defaulting to immature intel_pstate driver
oops, totally forgot this is still open, the problem turned out to be a completely stuck fan wrapped in filth ... cleaning it ave the system proper values so thermald does the right thing now. ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid ** Changed in: linux (Ubuntu Vivid) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1460399 Title: ivybridge system gets completely unusable after upgrade to vivid thanks to defaulting to immature intel_pstate driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1460399/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1460399] Re: ivybridge system gets completely unusable after upgrade to vivid thanks to defaulting to immature intel_pstate driver
one thing i noticed is that after dropping intel_pstate=disable from teh kernel commandline, thermald does not seem to star/run at all .. starting it manually i captured http://paste.ubuntu.com/11541063/ note that the behavior gets minimally better with thermald running, but switching workspaces is still as slow as about 20-30 sec in slow motion ... http://imgur.com/Ukuv34t shows one terminal with the script above and one terminal with htop running ... this is with thermald active ... the CPU normally switches between 800MHz and 2.8GHz with the ondemand governor in use ... with thermald i se it between 133MHz and at very short spikes up to 3.5GHz (but even when the cores run at that sped the system only gets responsive for a few seconds) turning intel_pstate back off gets me a relatively usable system back ... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1460399 Title: ivybridge system gets completely unusable after upgrade to vivid thanks to defaulting to immature intel_pstate driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1460399/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In Sandy bridge the system is not rendered completely unusable. But it still becomes hot, with fans constantly turning on and off, and the computer powering off from time to time.

just for completeness (in case someone looks for a wrokaround), adding intel_pstate=disable to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and running sudo update-grub got me the ondemand driver back and got the system back to behave as stable as in 14.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1460399 Title: ivybridge system gets completely unusable after upgrade to vivid thanks to defaulting to immature intel_pstate driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1460399/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
