linux-avmb1:Kernel Oops mit pppd,B1 PCI und capiplugin

Hallo Liste,

da doch recht ruhig um die Liste georden, produziere ich mal einen
Kernel Oops auf einem Debian Sarge 3.1r2 :-)

Nein, natürlich eher unbeabsichtigt.
ISDN Tools standardmässig über apt installiert, nur die Firmware von
meinem ehemaligen SuSE-System übernommen.

Bei der Einwahl via B1 PCI,capiplugin und pppd kommt reproduzierbar nach
dem Auflegen des Peers ein Kernel Fehler.

Hier der Fehler:
