I should add an extra interesting detail: if I plug the Wi-Fi device into a USB hub, instead of directly into the BeagleBone Black, then the kernel panic doesn't happen, and I'm able to use it successfully (although with other problems which I'll report in further e-mails).

I finally got around to trying a build of the kernel with that patch applied. However, it did not fix this problem. The device still causes a kernel crash when it is plugged directly into the USB port without a hub in between.

Yes, this is the exact crash which I used to hit. It is fixed by
following commit in wireless-drivers-next.git
8b4c0009313f3d42e2540e3e1f776097dd0db73d
(rt2x00usb: Use usb anchor to manage URB)
You may want to cherry pick the change and give it a try.

I have seen a similar crash and fixed it as a part of following commit:
8b4c0009313f3d42e2540e3e1f776097dd0db73d
But it would be helpful if you can get paste the entire kernel log.
Because in my case, I used to see a USB Disconnect event for the rt2800
driver and the crash was caused due to that.
Thanks,
Vishal

* rt2800 and BeagleBone Black kernel panic when connecting to access point

I have a D-Link DWA-140 USB Wi-Fi device which is rt2800 based (5392 chipset). I've been testing it on a BeagleBone Black running an Ubuntu 16.04 image (4.4.6 kernel).
1) Install Ubuntu 16.04 on a BeagleBone Black.
2) Add lines to /etc/network/interfaces for the device to connect to a WPA2 access point.
3) Plug the rt2800 USB Wi-Fi device into the BeagleBone Black.
Apparently when it tries to connect to the access point, I get a kernel panic. If I don't configure it (step 2 above) then the kernel panic doesn't happen.
I've tested this with two access points: my Android phone acting as a hotspot, and a cheap TP-Link TD-W8968.
Serial debug console shows:
