Comment 44 for bug 1437353

+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.
