No. ;-) But it's another issue. I'm loading the hisax drivers first:

hisax 492836 1
isdn 119072 1 [hisax]
slhc 4624 0 [isdn]
[...]

And after them (and the ippp-related programs..) the drivers for avmb1:

ppp_deflate 40928 0 (unused)
bsd_comp 4056 0 (unused)
ppp_synctty 4768 0 (unused)
ppp_generic 18240 0 [ppp_deflate bsd_comp ppp_synctty]
b1isa 3740 1
b1 17152 0 [b1isa]
capidrv 25716 1
capi 17344 0
capifs 3712 1 [capi]
kernelcapi 29796 4 [b1isa capidrv capi]
capiutil 22368 0 [capidrv kernelcapi]
[...]

I'm connecting with the avmb1-card to a provider via pppd and starting my iptables firewall (with qos scheduling). While connected or after shutting down the connection unloading the hisax or isdn modules produces that oops. I haven't tried it without the sched-modules loaded. Should I ? It seems that they could be responsible too.

Please note that the avmb1 (b1isa) card is active and hisax a passive one.

Hope that helps.
