Maybe it is only on ARM?

Bug description:
  [Impact]
  If you install Ubuntu onto USB storage behind a Platform USB host controller, it will not be able to boot because the generated initramfs will not include the host controller driver.

  [Test Case]
  Install to a USB stick attached to platform USB controller and reboot. Booting will fail because it will be unable to find the root file system.

  [Regression Risk]
  Driver is only loaded when system requires ehci-platform, minimizing the impact to all other systems.
