Hi Matthias,

the I4L and CAPI ISDN subsystem of 2.6 must be resynced and I hope
Karsten Keil is doing this very soon. For now apply the i4l-t9bk22 patch
and try again.

You have to load capi.ko by hand and mount the capifs.

Known problem, because the new modprobe complains with an error if a
module is already loaded. The CAPI utils needs to be patched.

Can't tell you why, but simply load it :)

Maybe the scripts need a little bit 2.6 cleanup.

> - when modprobing capidrv the console is flooded with messages

The capidrv itself is an CAPI application and the 2.6 CAPI subsystem is
a little bit talky, because the debug stuff is on by default.

> I use debian/unstable with the latest isdn and capi packages (3.3-7).

With the i4l-t9bk22 the CAPI part should work perfect.

Yes.

Not that I know of.

No.

Regards

Marcel
