This time when things stopped working I looked first before typing.
Radio went off. I had unplugged the notebook and closed the unit. But I
have done that earlier today. I plugged back in and while I was doing
lsmod and dmesg commands, the radio came back on. More likely not
related, just with power it 'woke up'? ARGH.
