I applied just this patch to wily's grub and tested on a thunder platform w/ AMI UEFI, and it appears to have introduced a regression. Where a MAAS boot would work successfully before, it now triggers a Synchronous Exception.
The attached script will create a grub netboot image the same way MAAS does. ** Attachment added: "script to generate a MAAS-like grubaa64.efi" https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1508893/+attachment/4502594/+files/make-image.sh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1508893 Title: TFTP timeout on ARM64 hw when booting from grub that was PXE loaded To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1508893/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
