With the newest git repo version of osmo-bsc, my nanoBTS fails to start.

I can confirm that they work normally with ip.access softBSC.


I thought osmocom Redmine issue #3063 might be relevant and tried
setting/unsetting force-combined-si but I am still getting the same
result. Attached are the packet capture and bsc config file

The following is the log from osmo-bsc:
