It happen on the 82573 and the 82546 depend on vlandev. To reproduce
this input command
ifconfig vlan557 create vlandev em1 vlan 557

But on client I see only requests without reply.
On GENERIC kernel reconnect is success. But down/up interface is not
right behavior.
Jack Vogel wrote:
Custom kernel, well, does it happen on the installed GENERIC kernel, and
what is needed
to reproduce this, just down/up the interface? And are you saying that it
will happen on
either the 82573 or the 82546 or just one of them??
Would be nice if this stuff could be discovered earlier :( In any case I
will look into it, there
is another reported problems with em and vlans as well.

Hi ALL !
I have several servers with FreeBSD 8.0-PRERELEASE on SuperMicro with
different Intel NICs. When I create new vlan on em interface
( ifconfig vlan557 create vlandev em0 vlan 557),
it hangs down and then up and server becomes inaccessible by ssh, but reply
on icmp request.
on amd64, custom kernel:
