Here I am in 2017, and it seems to be a regression bug. A bug that has come back, or perhaps it was never fixed and the user who reported it fixed, did so because it went from always crashing to intermittent crashing. A user will learn not to turn off wifi and the symptom goes away. I am using an Exomate and not only does it panic when turning off wifi but on startup it panics intermittently whenever you use a USB device you left plugged into it or plug in a USB device. After many power cycles and with periods of remaining off, the perpetual panics abate but I know not to turn off wifi now.
As a user, I am getting similar symptoms. And I see this is my symptom and it is not so aptly described in the link above. Although the cause may not be same, people are going to come here when they search, as I did.

Fix: Test for NULL pointer (patch from 2.6.31.5) --- When I disable the wifi using Fn+F2, the system hangs with a kernel panic instead of disabling wifi. I'll try to catch the panic message properly and attach it here (but the machine doesn't have a serial port, so it might take some hacking).
