Kernel panic at its best

Title explains everything. It was working correctly on 3.15.2. Both kernels were compiled with GCC 4.8.2 (Ubuntu 4.8.2-19ubuntu1). 

Steps to reproduce:
1. Start X
2. mplayer -vo vdpau -vc ffh264vdpau "[path to any 1920x1080 H.264 video]"
3. Switch to TTY1
4. weston-launch
5. Start Weston terminal.
6. Wait 10-20 seconds and start moving terminal's window.

Expected result: We see a moving window.
Actual result: We see a moving stack trace

I took a video of this panic. It might be helpful, as picture doesn't show whole stack trace. https://www.dropbox.com/s/l1mjskacm684gfr/VID_20140707_022416.mp4

Alex Deucher, you're probably right as I couldn't reproduce this on 3.16-rc6.
