** Changed in: initramfs-tools (Ubuntu Xenial) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1842284 Title: initramfs does not copy ehci-platform Status in initramfs-tools package in Ubuntu: Fix Released Status in initramfs-tools source package in Xenial: Fix Committed Status in initramfs-tools source package in Bionic: Fix Released Status in initramfs-tools source package in Disco: Fix Released Status in initramfs-tools source package in Eoan: Fix Released 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.
