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).
