[Bug 1790586] Re: The proposed grub package in Trusty overrides the boot order on a MaaS deployed ThunderX system

Tue Sep 4 11:13:28 UTC 2018

More test on the AMD Naples amd64 server "lodygin" shows:
1. This issue DOES NOT exist with this node deployed with Trusty.
2. This issue DOES exist with this node deployed with Trusty + T-LTS 4.4 kernel.
3. This issue DOES NOT exist with Xenial (no grub package in -proposed)
4. This issue DOES NOT exist with Xenial + X-HWE 4.15 kernel (no grub package in -proposed)
5. This issue DOES exist with this node deployed with Bionic.

More test on the ThunderX arm64 server "wright" shows:
1. (This node cannot be tested with Trusty)
2. This issue DOES exist with this node deployed with Trusty + X-HWE kernel.
3. This issue DOES NOT exist with Xenial (no grub package in -proposed though)
4. This issue DOES NOT exist with Xenial + X-HWE 4.15 kernel (no grub package in -proposed)
5. This issue DOES NOT exist with this node deployed with Bionic.

** Description changed:

  Similar to bug 1642298, bug 1750732 and bug 1788539

  This issue was only spotted on ThunderX Cavium ARM64 system and an AMD
  Naples amd64 server in this SRU cycle.

  Steps:
- 1. Deploy the ThunderX system with Trusty + X-HWE 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)
+ 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 at 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 at 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
