** Changed in:
Tested on x86 xenial-hwe. `update-initramfs` works and no ehci-platform
in initrd. System works fine after reboot.
ubuntu@zwicky:~$ sudo update-initramfs -k all -u
update-initramfs: Generating /boot/initrd.img-4.15.0-65-generic
W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
update-initramfs:
Has there been any testing performed on the architectures on which the
module is compiled in please, for example amd64? It seems to me that
this is a particularly important code path to test, since it is
identified as different and a bug could render regressed systems
unbootable.

What kernel is it that includes an ehci-platform driver? I'm not seeing
it in linux or linux-hwe in xenial.
