1. if not optimize the link in auto.c stage, and let hypertranport.c do the optimization, the hard_reset from reset_bus can works.... 2. if optimize the link in auto.c and hard_reset will be not called, and if call hard_reset from debug device....it works well. 3. if optimize the link in auto.c and reset freq to high value in hypertransport.c, the hard_reset from reset_bus will hang....
