I'm still having this problem after updating to 14.10. This issue exclusively arises if I suspend my laptop when connected to the power cord, then unplug it during suspend and wake it up on battery. It does not happen every time, maybe once in seven times.
The scaling_governor keeps all cores at "powersave". As soon as I replace that with "performance" through cpufreq-set the issue is solved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1264346 Title: [Dell Latitude E6520] After suspend, machine very slow with ondemand governor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1264346/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
