I don't know if this is the same bug, as I haven't bisected, but it appeared when I switched from a 2.6.26-rc8-wl kernel to a 2.6.26-wl one that contained the above patch. -- Vista: [V]iruses, [I]ntruders, [S]pyware, [T]rojans and [A]dware. :-) -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
