            Bug ID: 258319
           Summary: Network (em0) does'nt work not only in 13.0-RELEASE
                    but also in it's installer.
           Product: Base System
           Version: 13.0-RELEASE
          Hardware: i386
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: nctto14935@yahoo.co.jp

In 11.4-RELESE/i386 or before, network (em0, IPv4) works well (in base syst=
em
as well as in it's installer).  But in 13.0-RELEASE/i386, network does'nt w=
ork
not only in the base system but also in it's installer. I have confirmed th=
is
by three different methods as follows:

(1) Updating 11.4-RELEASE/i386 to 13.0-RELEASE/i386
freebsd-update works perfectly and it successfully upgrades 11.4 (of which
network works well) into 13.0, but network suddenly stops just after reboot=
ing
the system with 13.0 kernel.
(2) Network installation of 13.0-RELEASE/i386
The bootonly installer of 13.0-RELEASE works halfway.  It fails to fetch
13.0-RELEASE files from the internet (since network does'nt work) and final=
ly
ends with error messages.  This is a problem of 13.0 installer, but I feel =
this
problem stems from the same origin.=20
(3) DVD Installaton of 13.0-RELEASE/i386
The dvd1 installer of 13.0-RELEASE successfully installs 13.0-RELEASE, but
after rebooting the installed system, one finds network does'nt work.

In addition I have tried 12.2-RELEASE/i386 bootonly installer, and found th=
at
12.2 installer shares the same problem. (In contrast, 11.4 installer or bef=
ore
works perfectly.)

In 13.0-RELEASE/i386, network phenomena as follows are occuring:

(1) "ping hostname" ends with "Unknown host".
(2) "ping IP-address-of-host" works well.
(3) "ping localhost" works well.
(4) "ping IP-address-of-DNS-server" ends with "Host is down".
(5) "ping IP-address-of-gateway" ends with "Host is down"
(6) "ssh IP-address-of-host" from another computer fails.

I have confirmed these phenomena just after the clean installation of
13.0-RELEASE/i386.  According to dmesg messages, 13.0 kernel seems to recog=
nize
em0.  As for 13.0-RELEASE/amd64, I have never encountered the network probl=
em
like this.
