eth0: FIFO buffer overflow

Has anyone gotten any futher on this one? My RH5.1 box still crashes
only when I'm using it directly. It doesn't seem to crash as just a gateway any
I'm not seeing anything come to the console prior to the crash, but the IRQ of
my eth0 is always lit when it locks.. Anything I can check (I can send you the
from the diagnostic program, but the cards seem to check out okay.).. I'm using

a 905 and a 509, both 10/100tx..
