+1 with i350 NICs (many of them so this is consistently reproducible). We worked it around as follows (on the MAAS server):
cd /tmp wget http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/uefi/grub2-amd64/2.02~beta2-36ubuntu3.18/grubnetx64.efi.signed cp -p grubnetx64.efi.signed /var/lib/maas/boot-resources/current/bootloader/uefi/amd64/grubx64.efi It may or may not be necessary to reboot your MAAS server after doing this. `strings` tells me that the broken version, which was in /var/lib/maas /boot-resources/current/bootloader/uefi/amd64/ before we clobbered it was version 2.02-2ubuntu8.2, dated Aug 7. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1437353 Title: UEFI network boot hangs at grub for adapter 82599ES 10-Gigabit SFI/SFP+ To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1437353/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
