1. if not optimize the link in auto.c stage, and let hypertranport.c do the

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....
