I installed the 3.17 from the mainline kernels from that wiki page. Here's the uname -a:
Linux braindead 3.17.4-031704-generic #201411211317 SMP Fri Nov 21 18:18:15 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

It fails in a similar way:

The firmware page for the linux wireless for intel says that firmware
version 9 is used for 3.13+. The linux-firmware package only includes up
to version 8.

I will try with version 9 in a bit. The 3.17 kernel can also use version
10. I will try that as well.

Bug description:
  I am getting "Microcode SW error detected" constantly in my dmesg

  apport popups are not launching a browser when I say to report the
  bug. I am filing this bug with "ubuntu-bug linux". Hopefully, all the
  needed info is included. Please let me know if there is anything else
  I can provide.
