Hi,
         Some link state issues (getting confused 
about what port is up), problems at high packet 
rates.  I dont have this card in production, but 
in my test environment it was much more stable on 
RELENG_8 with the above patch in that I was not 
able to wedge the box.  pps rates were pretty ok on a low end i7 as well.
