Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.19 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:
  iwlwifi is not being loaded into the kernel on boot

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After upgrading some packages today the iwlwifi module stopped loading
  automatically after reboot which meant my wifi stopped working. No
  idea what package update caused it but here is what was updated (from
  the dpkg log)

  The wifi should work on boot. Eg. I should not have to: sudo modprobe
  iwlwifi

  The wifi did not work. The interface was not available.
