   I think, you overlooked the reseting of tp->probes_out in 
   tcp_input.c - tcp_ack()  to 0 with each ACK coming back from the receiver.
   tp->packets_out must be 0 - otherwise  the relevant code in tcp_send_probe0 
   would not be reached so the code jumps to the "no_queue" label.
   
And by mentioning this you unearth the real bug, tp->backoff needs
to be reset here where tp->probes_out is reset.

Can you make this change and see if this makes your problem
go away?

Alexey, anything missed here?  Maybe only reset tp->backoff when
tp->probes_out is non-zero at this point?
