In theory, you should *never* have an "ubuntu" entry in efibootmgr when MAAS-deployed. I'm guessing this is a dup of the following bug, for which a fix has not been backported to trusty: https://bugs.launchpad.net/maas/+bug/1642298

Steps: 1. Deploy the ThunderX system with Trusty + T-LTS 4.4 kernel (It works fine with just Trusty, however this was tested on the AMD Naples, not ThunderX since it does not support 3.13 kernel) 2. Check the efibootmgr output 3. Enable proposed, install grub-common 4. Check efibootmgr again Result: In step 2, the boot order is correct: ubuntu@wright-kernel:~$ sudo efibootmgr BootCurrent: 0002 Timeout: 10 seconds BootOrder: 0002,0000,0003,0004,0001 Boot0000* ubuntu Boot0001 UEFI: Built-in EFI Shell Boot0002* UEFI: IP4 Ethernet vNIC Controller 62:54:CA Boot0003* UEFI: IP4 Ethernet vNIC Controller 62:54:CB Boot0004* UEFI: IP4 Ethernet vNIC Controller 62:54:CC But in step 4, the boot order will be overridden: ubuntu@wright-kernel:~$ sudo efibootmgr BootCurrent: 0002 Timeout: 10 seconds BootOrder: 0000,0002,0003,0004,0001 Boot0000* ubuntu Boot0001 UEFI: Built-in EFI Shell Boot0002* UEFI: IP4 Ethernet vNIC Controller 62:54:CA Boot0003* UEFI: IP4 Ethernet vNIC Controller 62:54:CB Boot0004* UEFI: IP4 Ethernet vNIC Controller 62:54:CC ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: grub-common 2.02~beta2-9ubuntu1.15 ProcVersionSignature: User Name 4.4.0-134.160~14.04.1-generic 4.4.140 Uname: Linux 4.4.0-134-generic aarch64 ApportVersion: 2.14.1-0ubuntu3.29 Architecture: arm64 Date: Tue Sep 4 07:45:19 2018 SourcePackage: grub2 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1790586/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
