openSuSE 11.2 CAPI Problem mit AVM B1 PCI

14 Nov 2009

      Hallo openSuSE ISDN Liste,

ich benutze seit geraumer Zeit eine AVM B1 PCI ISDN Karte im
Zusammenspiel mit openSuSE und Asterisk, aktuell Asterisk 1.6.1.9 mit
chan_capi.
Bisher gab es keine Probleme, da die Module der Karte im Kernel
enthalten sind.
Mit dem neuen Kernel 2.6.31 der openSuSE 11.2 gibt es jedoch ein Problem
CAPI mit capiinit zu aktivieren.
Problem scheint zu sein, dass der Symlink /dev/isdn/capi20 auf /dev/capi
verweist, welches wiederum ein Verzeichnis ist.
Damit kommt dann capiinit nicht zurecht.

Viele Grüße

Arne
