Might the urtwn device overheat, not return & cause a panic ?
My urtwn device is very small, no thermal path to dump heat.  I've
not tried on current, but on 10.0-RELEASE I saw my urtwn0 interface
disappearing; I read parts of the driver; & noticed there's mention
of a temperature level, I didn't tweak it, but hung my device on a
USB extension cable at 10 C outside the window, & later in front
of a chassis input fan at ~ 20 C room temp., I think both locations
lasted longer or perhaps indefinately without urtwn0 , can't remember,
I suspended pursuing it.  Device picture for those who don't know
how small this, & other URLs via: http://www.berklix.com/~jhs/hardware/urtwn/

Cheers,
Julian
