Interrupt storm detected on "irq16: bge0 uhci0"; throttling interrupt source

Hi for all,

          I resolve install RELENG_5 in IBM x346, chance i've problems 
in usage two "Broadcom BCM5721 Gigabit Ethernet" in the same time, 
because irq storm is active, i not use acpi and when  disable one bge in 
setup, irq storm in the bge0 and uhci0 is active.
         In loader.conf,  set `hw.intr_storm_threshold=5000` but is the 
not help-me
