My init.d script does the following in short:

        modprobe mISDN_dsp
        modprobe mISDN_l1loop nchannel=30 interfaces=2
        sleep 1

        echo 1 > /proc/sys/net/ipv4/ip_forward
        iptables -t nat -A POSTROUTING -s 192.168.253.0/24 -o eth0 -j
MASQUERADE

        screen -S bsc -d -m su gsm -c "osmo-nitb -d
DRLL:DCC:DMM:DRR:DRSL:DNM:DSMS:DMNSMS:DPAG:DMUX -c /etc/openbsc/openbsc.cfg
-m -P"
        screen -S lcr -d -m su gsm -c "/usr/sbin/lcr start"

I'm using mISDN_l1loop.ko from current mISDN git because it was not included
in my kernel. Small patch to make it compile:

I could solve the above problem by a system restart. The mISDN_l1loop modul=
e was loaded but for some reason could not be used by LCR. The LCR error me=
ssage was:<br>
000000 ERROR loop port 1 failed to bind socket. (errno 93)<br>
<br>
<br>
By playing with the mISDN_l1loop module I discovered a strange problem. If =
I load the module with "modprobe mISDN_l1loop pri=3D1 nchannel=3D30&qu=
ot; all system memory is allocated by LCR after some seconds.<br>
<br>
If I load it with "nchannel=3D20" than everithing works fine.<br>
<br>
Can someone confirm this problem?<br>
