Building urtw(4) as module here helps a lot, kldunload/kldload is just so much
faster than a reboot. :)

I have a bunch of asorted fixes [1] for urtw(4) which needs some further
testing, though I still wasn't able to fix the issue which made me look into
this in the first place.. As a test case I force a disconnection from the AP
side a few times, which will eventually result in a device timeout and the
requirement to reload the module. I believe that one of those might actually
address the panic you're seeing, though, it doesn't fix the device timeout.
