I'm seeing this with a HP NC523SFP 10G NIC and MASS 2.4.0~beta2 on Ubuntu 18.04. If I UEFI boot from the NIC, it eventually brings up a grub shell. Taking a packet capture confirmed the same ARM storm behaviour when attempting to boot - thousands of packets from the server that is being commissioned requesting the MAC of the MAAS server. Running net_bootp from the grub prompt results in the "error: couldn't send network packet." error, and running net_nslookup for a domain results in an endless ARP storm!
Unfortunately, the last firmware release for this NIC was a few years ago and i'm already running the latest version. Reading the comments here, it sounds like my only hope is a fix within grub2 - however that should already be live. The version of grub booted is grub2 2.02~beta2-36ubuntu3.18, which according to the comments here should fix it. I've also tried using the 2.02-2ubuntu8 version of bootx64.efi, by grabbing it from http://archive.ubuntu.com/ubuntu/dists/bionic/main/uefi/grub2-amd64/2.02-2ubuntu8/grubnetx64.efi.signed and replacing /var/lib/maas/boot- resources/current/bootloader/uefi/amd64/grubx64.efi but with the same result. -- 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
