The latest kernel 3.16 driver doesn't Panic but it still has driver
failures that render the driver and device unable to scan and find
networks.
No need for a bisect since this driver is in staging, and is a work-in-
progress. For Trusty 3.13 kernel it may be necessary to disable building
the module since there is nothing we can do downstream to make it work.
[ 13.738475] rtl8821ae: module is from the staging directory, the
quality is unknown, you have been warned.

Title:
Kernel panic in rtl8821ae with 3.13.0-30
Status in “linux” package in Ubuntu:
Triaged
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).
