Bug description:
[Impact]
MAAS commissioning may fail when deploying Xenial images or using grubx64.efi
from Xenial due to hardware particularities of some Intel 82599-based network
cards. Other network manufacturers may be affected as well. The main failure
mode appears to be an infinite re-send of some packets because of an unexpected
response from the network hardware.
[Test case]
1) Attempt to netboot on a system with a "82599ES 10-Gigabit SFI/SFP+"
network adapter; in UEFI mode.
2) Validate that netbooting happens correctly, passing control over to the
kernel as configured in grub.cfg.
3) Validate that netbooting another system, not using an Intel 82599
adapter, behaves normally when booting in UEFI mode.
4) Validate that netbooting another system, not using an Intel 82599
adapter, behaves normally when booting in LEGACY mode.
[Regression potential]
As this affects network in EFI mode; any failure to netboot using EFI should
be considered a possible regression. Systems may fail to receive data from the
network boot server and terminate the process with a timeout. Another possible
failure scenario is to fail to receive complete data over the network, or data
corruption.
----
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.
