I just encountered a panic when the driver attaches after plugging in
the device.

The panic stems from uhso_attach(), and seems due to my kernel having
the VIMAGE option compiled in -- it doesn't panic on my non-VIMAGE
kernel (which I need to rebuild to continue helping debug).

I'm trying to get a textdump ATM...

OK, got it. See attached. Maybe there isn't sufficient locking applied
when working in vnet-enabled environment? Nevertheless, I'm building a
new kernel without VIMAGE to finish helping debug issue...
