Hello Jan.
Regarding the problem we discuss some time ago, it still remains.
I have until now found the origin of the problem.
Theres no RX interruption handled in any of the boards that should receive the
messages.
Thats why the stack_mgr_task never wakes up from the event.
I'm using the rt_8139too driver that cames with rtnet.
I've done some roll back in rtnet and RTAI and nothing:
Rtnet until version 1069
RTAI magma until RTAI-3.4-test1
Maybe can be anything related with RTDM and the interrupt handling.
