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

[Ante Karamatić]

I've replaced grubx64.efi from 16.04 with the one from 17.04 and problem
went away. This means that problem is indeed in grub or grub in 16.04
doesn't have needed workarounds for faulty firmwares.

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

Status in grub2 package in Ubuntu:

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.
