I got a BMC5722 chip (and IBM x3250 mX systems), but same stuff with 
timeout/resets. I can say 8.1/8.2 were more stable concerning bge(4).
You could try to switch off tso and vlanhwtso, at least it did the trick 
for me (did it ? not sure though. I was having problems one a month on 
8.1/8.2, after upgrading to 8.3-STABLE I start having problems with it 
every day, literally, after ifconfig bge0 -tso -vlanhwtso it's running 
for 5 day now.)
