[Bug 1564218] Re: Network is not working in Ubuntu Xenial installer for Gigabyte MP30-AR0 (APM X-Gene 1)

[Ronald Maas]

I tested with latest Xenial arm64 Mini ISO from http://ports.ubuntu.com
/ubuntu-ports/dists/xenial/main/installer-
arm64/current/images/netboot/mini.iso (dated 20-Apr-2016) and the
network adapter was not working.

When I passed the kernel parameter clk_ignore_unused, the network
adapter worked without issue. The installer successfully obtained an IP
address and was able to download all files required for installation.

More information about the use of clk_ignore_unused work-around and the
issues with xgene_enet when compiled as module can be found here:

Title:
  Network is not working in Ubuntu Xenial installer for Gigabyte
  MP30-AR0 (APM X-Gene 1)

Status in debian-installer package in Ubuntu:
  New

Bug description:
  When I start the Ubuntu Xenial Installer, the network adapter was not
  able to obtain an IP address. The installer was started from UEFI
  Shell using the command:

  FS1:\EFI\BOOT\BOOTAA64.EFI

  The xgene_enet ethernet driver does not seem to work properly when
  compiled as module. See more detail in another Bug Report I filed on
  the Debian EFI mailing list https://lists.debian.org/debian-
  efi/2016/03/msg00020.html

  Expected to happen
  -----------------
  DHCP server is able to assign an IP address to the network after which I am able to ping another system.

  What actually happened
  ----------------------
  Network adapter failed to obtain an IP address. No network connection is possible with other systems.

  Hardware
  --------
  Gigabyte MP30-AR0 motherboard with APM X-Gene 1 processor flashed with TianoCore UEFI
  Kingston KVR16LE11S8/4HB 16 GB ECC DDR3 DRAM
  HGST Deskstar NAS 6 TB drive
  Logitech USB keyboard

  Software
  ----
  Ubuntu Xenial Mini ISO downloaded from http://ports.ubuntu.com/ubuntu-ports/dists/xenial/main/installer-arm64/current/images/netboot/mini.iso (dated 29-Mar-2016)
  UBoot has been replaced by TianoCore UEFI using the steps described in: https://rwmj.wordpress.com/2016/03/08/gigabyte-mp30-ar0-flashing-uefi/

  Notes
  -----
  Both Centos 7.2 and Debian Testing were successfully installed on the system and running stable with full network connectivity (Centos out-of-the-box and Debian after recompiling the kernel)
