Can you try with this initrd.gz?
It's the amd64 initrd patched with a custom netcfg that will give a
slightly different debug output as well as try to flush all addresses
and routes on all interfaces prior to setup.
Would be great if you could test it and post the syslog.
Thanks

Title:
[oneiric] net-installer dhcp client fails with a DHCPDECLINE
Status in “netcfg” package in Ubuntu:
Confirmed
Bug description:
Installing recent oneiric builds via the net installer images fails. The first dhcp request to fetch the pxe boot image succeeds, as does the second before fetching a kickstart file.
The third and final time, however, fails with the client rejecting the lease with a DHCPDECLINE, repeating this over and over again.
I first started seeing this problem somewhere after the alpha-3
installer image, though I'm not sure exactly where. The
20101020ubuntu63 installer build fails.
Tracing through /sbin/dhclient-script it looks like the call in
BOUND|RENEW|REBIND|REBOOT) where it calls 'ip -4 addr add [..]' was
failing with a File Exists response. The old and new settings
appeared identical, however.
I managed to work around this by adding an unconditional call to 'ip
-4 addr flush dev $interface' in /sbin/dhclient-script right after the
call to set_hostname. With this workaround, all proceeds as expected,
though I'm not sure what the underlying problem is.
