--- Comment #5 from Tomoaki AOKI <junchoon_at_dec.sakura.ne.jp> ---
Can Bug 253172 [1] be related with this?

 Bug 253172 - Intel e1000 - Interface Stalls After Media Type is Changed

With this bug, second if_em (em1) causes hang.
And with Bug 253172, second attempt with ifconfig up (different media type
used) causes interface stall.

Just a thought, but if this affects even if the port is different (whichever
port or media type is different on if_em driver causes same issue), and if the
em1 is configured to use DHCP, possibly em1 wait for DHCP reply, which never
comes into, and thus locks up.


Not reading the if_em (e1000) codes nor iflib codes, I could be
mis-understanding, of course.
