Hi all,

I am trying to netboot using cobbler + PXE + TFTP, everything works fine except
that DHCP auto configuration fails.
I can see on the logs tha

before the problems mentioned above were fixed, but I just tried doing
that now and it works for me.

I'm still seeing a problem doing DNS look up even after this seems to be

If, when trying to download a kickstart config by DNS, it immediately
fails. I can see it go through the process of getting an IP, then it
attempts to get another IP again. I know if i swap to a different tty

Just done running a few tests and didn't find any regression, though that was
just with a standard:
- Start the installer
- Let netcfg run automatically
- Download components
- End of test
I only tried once to get back to netcfg from a later point and it seemed
to work fine too.

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.

Yes, I do still see the same problem with the current kernel and initrd.
I also tried creating a VM here and pxe-booting it. I do see the same

Yes, I have a PXE & DHCP server serving out the netboot kernel and
initrd.gz file, as copied from the mirrors in ubuntu/dists/oneiric/main

Ok, so just to make sure I understood your setup correctly.
You have a PXE server (DHCP + TFTP) serving the content of
netboot.tar.gz with I'm guessing a kickstart/preseed value set on the
kernel command line pointing to a kickstart file available on the
internet?
Can you attach your /var/log/sys
A possible cause that comes to mind would be the IPv6 support changes in
