[asterisk-dev] mISDN problems

[Enrico Pasqualotto]

Hi all,
we're buildin an Asterisk box based on an Intel IXP425 board.
The board uses a Beronet BN2S0 ISDN card, mISDN 1.1.4 and asterisk 1.4.2.
hfc_multi has been patched to compile under big endian cpu, and so also
capi kernel files.
All the modules seem to load correctly (configuration was made with
misdn-init config), but when starting cha_misdn, asterisk outputs the
following lines:
P[ 1] Restarting this port.
P[ 1] Stack:0x174f10

This error is generated by a function into asterisk package in file
channels/misdn/isdn_lib.c

misdn-init start output:

mISDN_dsp: DSP clocks every 160 samples. This equals 2 jiffies.

The only output that we see when interacting with a phone connected to a
PBX is a string like

0x64 0x7f 0x01

but it seems more related to layer1.

Once we have seen an error from mISDN_read, coded 22, but never have been
able to reproduce it.

The same configuration on x86 work perfectly.

Any idea?
