have you ever looked at those event reports using the abis_oml wireshark dissector from openbsc.git/wireshark/ ?
this should give you some more information than just the BSC log.
Yes but i couldnt locate the problem. I'm not that familar with the oml protocol, maybe i miss something. I uploaded the pcap if somene is interestet. http://luusa.org/~derpeter/nanoBTS-reboot.pcap
