There is no initialization packet to send streams; however, it might be a problem who is the cycle/bus/IR manager. Can you see some difference of the output of the fwcontrol(8) and demsg(8) in node-id, cycle master and etc. between success and failed cases? Thanks for a fix for the compiler warning.
