Public bug reported:
This issue was spotted on our Cavium ThunderX ARM64 nodes, with MAAS
version: 2.2.2 (6099-g8751f91-0ubuntu1~16.04.1)
Steps:
1. Deploy Xenial on this ARM64 node with MaaS web UI
2. Check the BIOS setting to make sure it's booting with PXE
3. When it's been deployed, check the efibootmgr output:
$ sudo efibootmgr
BootCurrent: 0002
Timeout: 10 seconds
BootOrder: 0004,0002,0003,0000,0001
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
4. Enable -proposed pocket and upgrade grub2-common and related packages
5. Check efibootmgr again:
$ sudo efibootmgr
BootCurrent: 0002
Timeout: 10 seconds
BootOrder: 0000,0004,0002,0003,0001
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
You can see that the BootOrder has changed here.
