linux-avmb1:kernel crash during heavy load - capi ppp plugins - avm b1 - isa or pci

Moin,

wenn ich meine AVM-B1-Karten voll auslaste, dann schmiert mir der Kernel 
ab. Habe im Netz nichts vergleichbares gefunden, offensichtlich scheint 
CAPI bei Linux-Anwernden aber fast ausschließlich für FAX verwendet zu 
werden. Mein Problem betrifft aber die PPP-CAPI-Einwahl. Vielleicht ist 
es ja auch der PPPD, wobei der mit einer passiven i4l-Karte keine 
Probleme macht. Auf der Console steht etwas von "Unable to handle kernel 
paging request". Wäre nett, wenn mir jemand helfen könnte.

Mein System:
# cat /proc/capi/driver
b1isa                            1.1.2.3
# cat /proc/capi/controller
1 b1isa      running  b1isa-150        B1 3.11-03 0x150 3 r2
# ll /usr/lib/isdn/b1.t4
-rw-r--r--  1 root root 254657 Sep 15  2003 /usr/lib/isdn/b1.t4
# md5sum /usr/lib/isdn/b1.t4

# uname -r
2.6.7-gw
// Debian 3.1
// ppp 2.4.2+20040428-2
// pppdcapiplugin 3.3.0.20040704-0.4

In einem anderen Rechner läuft eine B1-PCI-Karte. Gleiche Symptome. Bei 
beiden Rechnern gab es keine Probleme unter linux-2.4.x

Danke im Voraus,
Jörg
