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:

Okay, see the attached file. I can't see a USB Disconnect event for the rt2800, until the end (line 561, timestamp 222.861630) which is when I unplugged the USB hub.

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,

The attached file seem to report a different kind of crash (soft
lockup) while the crash reported in the 1st email of yours is
different (NULL pointer dereference).
I am not sure about this soft lockup problem though.

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.
