dP of YBa2Cu408 single crystals has been measured up to 9 GPa under hydrostatic pressure. The large and positive initial value (dTc/dP)o= 5.5 K/GPa is confirmed. To(P) saturates above 5 GPa. Dramatic changes, in the Tc(P) behavior are observed when the pressure is non-hydrostatic. They are caused by
