Kernel PANIC often when turning WiFi off, on current 3.19.0-27-generic (see text, my be one older), happened before on previous kernel, and one or two, probably more, before that one.

Bug Description
When opening lots of network connections and disconnecting from WiFi I get two light blinkning (CAPS LOCK light and the one to it's right) - assuming kernel PANIC.
[As Google Chrome opens a lot of tabs, when starting, I've used the trick of disconnecting WiFi for a while (and sometimes killing Chrome processes, but not this time I believe, but it shouldn't matter), to get it to avoid OOM.]
This is not the first time I've gotten a kernel PANIC this way or the only kernel (may be a few versions back). I assume this is a bug in the kernel (also), but also in (proprietary) wl:
lsmod |grep wl
