Package: initramfs-tools
Version: 0.116

Hello,

running Debian with the root filesystem on a USB mass storage
device (such as a USB harddisk) requires that the driver modules
for the USB host controllers of the system are available in the
initramfs.  If they are missing, the root filesystem cannot be
mounted, which currently happens on a number of armhf systems.

On i386/amd64, the OHCI/EHCI host controllers are PCI devices
which are supported by the ohci-pci and ehci-pci modules.  On
many armhf systems the USB host controllers are
OHCI/EHCI-compatible, but implemented as a platform device, so
they are not supported by ohci-pci and ehci-pci.  Instead these
systems need the following platform device driver modules:

- ohci-platform
- ehci-platform

and in the case of armhf/sunxi-based systems an additional
USB phy driver module:

- phy-sun4i-usb

These modules are not included in the initramfs built by
initramfs-tools (even if MODULES=most is set in initramfs.conf),
which makes it impossible to boot with the rootfs on a USB disk
on such systems.

Please always include ohci-platform, ehci-platform and
phy-sun4i-usb into the initramfs if they are provided by the
kernel for which the initramfs is built.

Regards,
Karsten
