Sterbender I4B Router

Moin,

ich glaube, mein 10 Jahre alter I4B Router möchte in Rente gehen.
Innerhalb hat der letzten 24 Stunden hat sich die ISDN Leitung
zweimal, mit Meldungen wie den unten, verkantet und ließ sich nur
durch eine Reboot deaktivieren. Nun fehlt mir leider das Wissen,
um die I4B Kernelmeldungen genau einzuordnen aber gut sieht das
nicht aus.

Was mich außerdem noch stutzig macht, ist die Tatsache, daß ich
seit dem ersten Aussetzer auch Probleme mit der eingebauten
Netzwerkkarte (fxp) habe. Es kommt zu Paketverlusten bis zu 80%
obwohl in dem betroffenen Subnetz, mit Ausnahme des pings, keine
Daten transportiert werden. Bis dato lief alles problemlos.

Der Rechner ist in betagter Pentium mit einer ISA Teles ISDN Karte
und einer Intel Netzwerkkarte. Auf dem System läuft FreeBSD 4.6-STABLE.
Dienste laufen auf dem Rechner nicht. Die Last ist nicht gewaltig.

Was ist die Ursache für die i4b Kernelmeldungen? Gibt es einen
anderen Grund außer Probleme mit der Hardware? Gibt es eine Methode,
mit der man den Fehler eingrenzen kann?

Hier die Meldungen:
