Confirmed, I just updated to a 3.0 kernel (3.2.0-24), and this problem

If needed, I can do a debug build and step through this, but I'd
rather not, if someone can identify the issue first.

So do you think this is related to the monitor-mode problem that Henri
also saw?

I suspect it is because the interface doesn't have an IPv4 address. Do
you have a "mon1" interface in ifconfig output also?
David the part of the code that is failing as described in Henri email is
when the code is copying and converting the hardware address.

It should use the memcpy function.
