[Wien] Fonera Kamikaze mit Funkfeuer

[(spam-protected)]

Hallo Leute,

Bei mir treten im log sporadish (alle 2-36h) folgende fehlermeldung auf. Wenn das passiert, ist keine funk verbindung mehr vorhanden, weder auf layer 2 noch auf hoeheren layers (layer 1 ist so scheints ist noch vorhanden da ein RX signal vorhanden ist). Es hilft lediglich ein reboot, bzw ein neustart des ath0 interface und des olsrd. Das ist aber auch nicht immer erfolgreich.

Es passiert oefters wenn viel funk traffic in der luft ist, was den "no xmit buf" erklaeren wuerde...

Nach ein wenig googeln hab ich heraus gefunden dass dies eine sache mit dem atheros treiber zusammenhaengt, aber loesung hab ich noch keine gefunden. Hat von euch jemand ein aehnliches problem? Bzw ein loesung?

Thx.
