From my experience, no. My init.d script does the following in short:

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

Hi,
I solved the memory allocation problem. It was the interface configuration from LCR. To work properly I had to remove the [Ext] and [Int] section in the file /usr/local/lcr/interface.conf
This was indicated by a error message in LCR during start: 000000 ERROR Port 1 already in use by LCR. You can't use a NT port multiple times.
All necessary steps for a working OpenBSC + LCR setup can be found in the step by step guide here: http://lab.ks.uni-freiburg.de/projects/gsm/wiki/Openbsc_lcr
@Andreas: Can you apply the mISDN patch from Lennart to the mISDN-Git? Than everything compiles and works properly.
Best regards Konrad
