The test scenario was PPP over ISDN with pppd+capiplugin. In an alternative scenario, also PPP over ISDN but with smpppd+capidrv, the message did not occur. Johannes' answer pointed me to the netif_rx() function. The Gigaset driver itself doesn't call that function at all. In the scenario where I saw the message, it was the SYNC_PPP line discipline that did. But from your explanation I gather that the cause cannot lie there. So now I'm looking for other possible causes of that message. - -- Tilman Schmidt E-Mail: tilman@xxxxxxx Bonn, Germany Diese Nachricht besteht zu 100% aus wiederverwerteten Bits.
