["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Laurent Bonnaud, thank you for updating your BIOS. Could you please
confirm this issue exists with the latest development release of Ubuntu?
ISO images are available from http://cdimage.ubuntu.com/daily-
live/current/ . If the issue remains, please just make a comment to
this.

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-3.13

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  [Dell Latitude E6520] After suspend, machine very slow with ondemand
  governor

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After several suspend/resume cycles and several days of uptime, using the ondemand governor the system is very slow to answer some inputs. The text output pauses for several seconds while I am typing this text. Trying to scroll a firefox window takes several seconds. Switching tabs in firefox takes several seconds:
  cat /sys/devices/system/cpu/c*/cpufreq/scaling_governor
  ondemand
  ondemand
  ondemand
  ondemand

  WORKAROUND: Setting the governor to "performance" fixes this problem.
