We believe we have isolated and fixed this issue.  The fill will be
rolled into build #302.

It was apparently caused by another patch that fixed the 'iperf' bug on
the mesh interface:

http://dev.laptop.org/git.do?p=olpc-2.6;a=commitdiff;h=2b9aaacb4e32a7f100c228beaca3e3a6459e2121

which stopped the eth wireless device's transmit queue before a scan,
but failed to re-enable it afterwords.  NetworkManager gets hit by this
bug since it actually runs periodic scans.
