Not being adventuresome enough to try T1, I waited for T2 (though I
download T1 torrent to help make it available to others braver than I...
but I digress)
I have FC3 running on a Toshiba Satellite 1115-S103 laptop.
I did an upgrade using FC4 T2 DVD and the install/upgrade went fine...
no problems.
When it ejected the DVD and I pressed "reboot", it was unable to bring
up eth0... FAILED.
I tried to configure the network manually, and saw that I could not
select DHCP for that interface, so I coded a static address that I knew
was available on my home LAN. (The same address FC3 was using before the
upgrade)
service network restart was still unable to bring up the interface. :-(
Then I tried my 3COM 3CXFEM656C card (10/100, not wireless) (which works
fine with FC3) but I was unable to get that working either.
I decided to try the install again from scratch, wiping out everything
in case there was "something funny" with upgrading from FC3....
Long story short... same result.
I chose "no firewall", selinux=warn, install everything
I didn't know where to look for logs that might show me more detail than
"failed", but I was able to tell that FC4 could tell the difference
between the Ethernet cable being connected or not.
When it was disconnected... I got an error like "no connection, check
cable".
When it WAS connected, I'd get a message like "acquiring IP address
information"... and it would time out eventually.
I gave up, did a clean install of FC3 again, and all was well.
Sorry I can't provide any more specific information about the eth
interface failure... but something that works in FC3 is now broken in
FC4 T2 regarding the Ethernet interface. :-(
