[Asterisk-Users] mISDN & kernel 2.6.9

[Thomas Jagoditsch]

hi all.

ive got a problem implementing my own small office asterisk solution.
i want to use
- a hfc-card via mISDN in NT-mode to serve my siemens gigaset 3035 isdn 
phone
- an avm b1 to connect to pstn
- sip, iax etc.

working:
- chan_capi via the b1 works fine, i can dial in and get the demo
- sip, iax - no surprise

failing:
- chan_misdn via the hfc card

problem:
asterisk crashes with a mysterious message i found no information on the 
net about...

> test root# asterisk -vvvgc
> [...]

i cant find no information about that "cannot request MGR_NEWENTITY from 
mISDN: Illegal seek" message anywhere and have no idea what to do next.

environment:
- celeron III
- acer isdn 128 surf pci
- avm b1,  firmware b1.t4
- gentoo (recent, no nptl)
- kernel 2.6.9 patched with 
http://home.foni.net/~jolly/download/mISDN_for_PBX4Linux-2.5-fix1.tar.gz 
(tried yesterdays CVS too)
- mISDNuser from 
http://home.foni.net/~jolly/download/mISDNuser_for_PBX4Linux-2.5.tar.gz 
(tried yesterdays CVS too)
- chan_misdn-beta-0.0.3-rc2.tgz (recompiled always after mISDN* & kernel 
changes)
- asterisk 1.0.2 (gentoo ebuild)
- chan_capi.0.3.5.tar.gz

/dev/mISDN is there:

> crw-r--r--  1 root root 46, 0 Nov 18  2004 /dev/mISDN


what i have tried so far, same error:
- unloading the b1,  capi etc and using mISDN only
- using mISDN & mISDNuser from CVS
- enabling/disabling apci/acpi

tried too:
- using pbx4linux to test mISDN:
    pbx query says no cards found !?!
    pbx start claims above error message (cannot request MGR_NEW...) too !?!

so, for me it looks like mISDN has a problem on my system - but otoh the 
drivers load nicely, see:

i even got some kind of confirmation that the hfc-driver can communicate 
over the "internal" bus at least.
if i do something on the gigaset phone i will get messages like ...

> dchannel_bh: event 1
> dummy_if: hif(ceaba148) skb(ce959ea0) len(8) prim(110282)

> dchannel_bh: event 1
> dummy_if: hif(ceaba148) skb(ce959c60) len(8) prim(110282)


etc.

has anybody out there a clue what i could have made wrong ? or what i 
could try next ?
