Description

It was first noticed by neels that in build#945 [1] we got more failed test cases than usually. Now I see similar failures in build#949 [2]. The build aftifacts in both cases look really suspicious: it seems like osmo-bts-trx did not even try to establish any OML/RSL connections [3]. The packet captures [4] contain no A-bis traffic at all. What's even more strange is that osmo-bts-trx was scheduling Downlink bursts even without being connected to the BSC. This needs to be investigated.
