I run a 6.1-RC (as of Apr, 14th) and after a day nothing can be sent =
from em interface.
It is a filtering+accounting bridge-on-a-stick, with em interface =
connected to 3Com Switch 4200 100Mbit (not Gbit) port with 4 tagged =
vlans on it:

Polling was not used (I'll try to work with polling enabled on em0).
ALTQ is not configured, pf has all block rules logged and I can't see =
anything relevant logged to pflog.
This machine also use netgraph netflow for traffic accounting on vlan =
interfaces, but shutting down all netgraph nodes does not help.
Turning vlans, bridge and em down and up does not help too.
Traffic is received (I can see pairs of OSPF HELO messages from ISP =
router logged on pflog0 exactly every 10 seconds), but it looks like =
nothing can be sent.
