Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

Title:
  [Lenovo Thinkpad T440S] frequent nm crashes and problems

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hello there,

  since I have freshly installed Ubuntu 14.04, Network Manager seems to
  have more problems handling 3G connections than under 13.10:

  1) The PIN code is not remembered. Even when I tick the "Unlock
  automatically" option and also input the PIN in the connection
  settings, the system asks me for the PIN on every startup. It is
  especially annoying because the dialog for the PIN also appears on the
  login screen and takes the focus away from when you are typing the
  password.

  2) Malfunctioning connection interface. After the PIN has been entered, "Enable Mobile Broadband" has to be ticked in the nm-Applet. However, I always have to do this twice before the check-icon actually appears and I can connect.
  When connecting, there is no indicator that the connection is being set up, instead the applet's icon shows the "not connected" empty triangle.

  3) Connecting after suspend/resume does not work reliably. However, as
  there are more problems with suspend/resume on the T440S with 14.04,
  this will probably have to be dealt with separately.

  As mentioned above, I have installed Ubuntu 14.04. I am using Unity
  and network-manager-gnome in version 0.9.8.8-0ubuntu4.

  I realize that you will need further information. Please let me know what you need to know in order to investigate the problems I have described.
