Mark Howell, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc3

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

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

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:
  8086:088e [System76 gazp7] iwlwifi: Microcode SW error detected

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This smells like bug #1099487 but is on a Precise kernel
  (3.2.0-37-generic #58) rather than a Quantal 3.5 kernel.

  I get this on boot now, possibly since updating to -37.

  The system is a System76 gazp7 laptop (Core i7-3720QM according to
  /proc/cpuinfo) with an Intel Centrino Advanced-N 6235 wifi adapter
  (according to lspci)

  dmesg output:
