There are multiple possibilities, could you please double check the ifconfig output on both -8 and -9 and verify that the negotiated media types are identical? Same for offload features? Another possible issue is a switch from single interrupt to multiple msi (and bugs in that area). If you check your -8 and -9 dmesg you should see details printed about interrupts routed to the bge interfaces (not sure if you need to boot -v for that nowadays). Martin
