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:
Won't Fix
Status in linux package in Ubuntu:
Invalid

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:
