David Coles, could you please test the latest upstream kernel available from the very top line at the top of the page (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:
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-3.16-rc6

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.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-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:
  [Gigabyte GB-BXi7-4470R] Kernel panic in rtl8821ae

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After updating the system to linux-image-3.13.0-30-generic (trusty-
  updates), the encounters a kernel panic during boot in the rtl8821ae
  module. This prevents the system from booting.

  This appears to be an issue relating to the mPCI WiFi+BT module
  (Realtek Semiconductor Co., Ltd. RTL8821AE 802.11ac PCIe Wireless
  Network Adapter) included with the system.

  A workaround is to boot using the older linux-image-3.13.0-24-generic
  (trusty).
