I'm still seeing this bug as well. Both Ubuntu 16.04 LTS and 15.10 netboot kernels produce this behaviour.
When IP-Config starts configuring the NICs, I see the DHCPDISCOVER arriving on the DHCP server, DHCPOFFER is going out, but no ACK is being received and the client continues telling me "IP-Config: no response after x secs - giving up". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1327412 Title: Delay during PXE Boot, IP-Config gives up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/klibc/+bug/1327412/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
