is there more than one network interface in your machines? If there is,
either disable the unused one in the bios during the installation or give the
name of the used interface in front of the last colon in the ip= kernel
command line parameter.
background:
if you have more than one network interface and use kernel-level ip
autoconfiguration without restricting it to one interface, it issues dhcp
requests on all interfaces which of cause time out on the unconnected ones...
