[Bug 1917665] Re: PXE booting exits into grub command-line

[Camille Rodriguez]

The maas version is the snap 2.8/stable (2.8.4-8597-g.05313b458) and the
image stream is the default one that comes with maas.io for 20.04 and
18.04. I'm not sure how to determine which image stream or bootloader
revision comes with that from this website
http://images.maas.io/ephemeral-v3/stable/. If there's a cli command I
can run to find out, let me know.

This is with UEFI.

Title:
  PXE booting exits into grub command-line

Status in MAAS:
  New
Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  On Dell Poweredge R740, commissioning from MAAS fails because the PXE
  booting process does not start properly. It exits into the grub
  command-line quickly after attempting to PXE booting over IPV4.

  The only workaround working so far is to connect to the remote console
  during the commissioning phase, wait for the grub command-line, then
  type "exit", enter, and then the PXE booting resume correctly. This
  forces a manual interaction for every server commissioned through
  MAAS, which slows down considerably a deployment.

  MAAS version: 2.8/stable: 2.8.4-8597-g.05313b458
  Commissioning images affected: 18.04, 20.04.2, with default kernel and hwe-edge kernel
  Integrated NIC : Intel(R) Ethernet 10G 4P X520/I350 rNDC (PXE over port 3) version 19.5.12
  Dell BIOS version: 2.10.0

  Thanks for the help
