After perhaps 20 minutes or so, it's able to go on and the memtest
completes, but some processes still remains:

Title:
  update-grub (grub-probe) during package installation on Cisco UCS B260
  servers - Precise deployment fails with hwe-t kernel

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  In bug 1437475, deploying Precise with maas was failing with curtin
  error with generic ephemeral image.

  With hwe-t kernel it gets passed the curtin error.. However, grub
  looks to be stuck. Looking at the diff for install log minutes apart
  right before deployment gets marked as failed by maas, it looks to be
  retrying the last step:
