[Bug 1455268] Re: update-grub does not complete for deployment of Precise with hwe-t kernel and Cisco UCS B260 servers

Using the same cisco system, I deployed trusty. I then installed a
package and installation of the package around the same location. I then
found that it was hanging in grub-probe. I kill that process a couple of
times and the installation proceeded and completed afterwards. The
Killed message showed that it was the right grub-probe process that I
killed.

going back to the ps -ef output from the log that I included earlier, I can see that it's the same exact issue that prevented the deployment from completing:

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:
  New

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:

  Last lines of curtin install log:
