[Bug 1091718] Re: 3.7 kernel and network manager do not play nicely in kubuntu raring


fejes, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you 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:

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

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:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

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

  3.7 kernel and network manager do not play nicely in kubuntu raring

Status in “linux” package in Ubuntu:

Bug description:
  Sorry - Ubuntu-bug didn't give me suitable options, and clearly some
  of the information it's reporting is just incorrect .

  I upgraded kubuntu 12.10 to 13.04 last night, and observed the update-
  initramfs bug
  (https://bugs.launchpad.net/ubuntu/+source/kmod/+bug/1073062).  Upon
  restart, KDE loads, but NetworkManager takes 100% cpu, and fails to
  allow wireless connections. (Changing the backend from NetworkManager
  to Wicd does not help.)

  However, if you restart and select the 3.5 kernel instead of 3.7
  kernel, the problem disappears completely.

  I'm happy to help debug and provide further information if you can
  tell me what it is that's needed.
