[Bug 1437353] Re: UEFI network boot hangs at grub for adapter 82599ES 10-Gigabit SFI/SFP+

[Russell Jones]

We're seeing this (or something very similar) on an Intel X540 10GbE
Dual port Mezzanine adaptor (Intel 82599 Controller) in a Dell server.

I'll follow up with firmware revision numbers when I have them. It'd be
helpful if others who've hit this provided them as far as they can.

Does this patch look like it would fix/work around it?
http://git.savannah.gnu.org/cgit/grub.git/commit/?id=4fe8e6d4a1279b1840171d8e797d911cd8443333

I'm having a go at applying it to the Xenial version of grub2, in
particular to build grubnetx64.efi We'd be interested in the results if
anyone else is able to test this.

Title:
  UEFI network boot hangs at grub for adapter 82599ES 10-Gigabit
  SFI/SFP+

Status in MAAS:
  Invalid
Status in python-tx-tftp:
  Invalid
Status in grub2 package in Ubuntu:
  Invalid

Bug description:
   I am using MAAS to commission and install machines. When I attempt to commission a machine with a "82599ES 10-Gigabit SFI/SFP+" network adapter the following happens:
  1) TFTP Request — bootx64.efi
  2) TFTP Request — /grubx64.efi
  3) Console hangs at grub prompt

  If I go into bios and force the adapter above into legacy mode then the machine is able to network boot and run through the commission process.
  1) TFTP Request — ubuntu/amd64/generic/trusty/release/boot-initrd
  2) TFTP Request — ubuntu/amd64/generic/trusty/release/boot-kernel
  3) TFTP Request — ifcpu64.c32
  4) PXE Request — power off
  5) TFTP Request — pxelinux.cfg/01-90-e2-ba-52-23-78
  6) TFTP Request — pxelinux.cfg/71e3f102-bd8b-11e4-b634-3c18a001c80a
  7) TFTP Request — pxelinux.0

  Also, if I disconnect the cable to the adapter above and connect a
  cable to the integrated "I210 Gigabit" adapter which is configured for
  UEFI mode. The machine is able to network boot grubx64.efi and run
  through the commission process.
