Please send output from 'ifconfig wi0'.
Also, please break into the debugger next time a hang occurs, and send
me the stack trace.
BTW, wi is in need of an overhaul where it does not busy loop while it
waits for commands to complete. Instead it should tsleep() in the top
half, or frob a state variable and return in the bottom half. That will
end the annoying system pauses on PCI/PCMCIA wi and help us to add a
USB front-end to wi.
No fewer than two people have told me that they would do the overhaul
write a USB front-end. I do not remember their names. Maybe I just
dreamt it. =)
