Hi Marcel et al,
could anyone give a hint what changes are necessary from kernel 2.4.X to
2.6.X to get an isdn dialup setup via cmtp and capidrv (i4l)?
I have a very well working setup for 2.4.22-mh2, essentially following
Marcel's (BTW excellent :) instructions from
http://www.holtmann.org/linux/bluetooth/isdn.html and had a quick try
using the same setup on an unpatched 2.6.2-rc2 vanilla kernel, getting
the following symptoms:
- cmtp and kernelcapi are loaded and connecting to an AP-X works
- capiinfo and capiinit complain about not being able to load
kernelcapi, although it is already loaded
- capidrv isn't loaded automatically any more
- "/etc/init.d/isdnutils start" complains about /dev/isdnctrl (because
of missing capidrv?)
- when modprobing capidrv the console is flooded with messages
I use debian/unstable with the latest isdn and capi packages (3.3-7).
Do I need any kernel patches (e.g. the i4l patch from
http://rcum.uni-mb.si/~uvp00845b/)?
Do I have to modify the module loading definitions in /etc/modutils?
Does pppdcapiplugin work without additional kernel patches?
Regards.
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.

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.

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

Yes.

Not that I know of.

No.

the full ISDN update for 2.6 is much bigger.

Thank you for your hint, I tried again and it seems to work now :)))

Ok, that's one that I missed.

Well, I had to learn that there is the directory /etc/modprobe.d first...

Don't think so, that was due to the missing capidrv.

Seems to :)

Well, I copied them to the new /etc/modprobe.d, e.g.:
alias char-major-43 capidrv
alias char-major-44 capidrv
alias char-major-45 capidrv

But it seems to with the i4l-t9bk22 patch :)
Cheerio
