Hi Harald,

I have one problem with the BTS on cold start. OpenBSC is sending the RSL 
connect, Radio Carrier/Baseband attributes too early and we are receiving 
NACKs from the BTS and the RSL link is never established.

The first question is if others have seen this problem? I have solved the 
problem my moving the OP start/set attributes/RSL connect of the RC and 
Baseband out of the state change code into the "Software Activated Report".

Doing a quick check it seems to still work and solve my cold start problem. Do 
you think this is a legitimate workaround for the problem right now?

In the future we probably should attempt to have a better state machine, 
report errors, retry and such things...

regards
	holger
