OK this stuff is hard to reproduce it seems.. you have an Atheros AR5418 MAC/BB Rev:2 AR5133 RF Rev:81, what kconfig option do you use to get the poison stuff? I am just surprised we haven't seen it ourselves yet. Let me make sure all of us get this kconfig option enabled.

Oh I mean the config options to enable the poison rant.

From what I remember all I was doing was switching from one wireless network to another (then opening firefox to sign my life away). eventually giving up, realizing I needed 99 big ones to be back on the grid. (beauty of git though is I don't need to be online to work). Justin P.
