Fully oxygenated ceramic YBa2Cu307\_6 has a non-linear resistivity [p (T) ] reminiscent of the resistivity Pb (along chains) in untwinned single crystals. The excess resistivity above 200 K, measured with respect to the linear portion of p(T) is activated. We suggest a Frenkel-disorder process, in w
