Are there any other systems that use flash-kernel that need to be
considered in the test plan and regression potential sections?

>From a flash-kernel perspective, based on the patch it seems to me that
the decision to use a compressed kernel is outside the package, so I
don't see a regression risk there. But other systems should be
considered when landing the change that actually causes kernel images to
be compressed, I think.

X-Gene is the only arm64 SoC that I'm aware of that uses flash-kernel and
the Ubuntu generic kernel. The switch to compressed kernels was specific to
the Ubuntu arm64/generic kernel.

WRT the change in the kernel package to make images compressed, it has been
regression tested across the non-flash-kernel (i.e. UEFI) servers (GRUB
handles the decompression). This change is also restricted to the hwe
kernel in xenial, so it has no regression risk for those running the GA
kernel.

Both the kernel and flash-kernel changes were shipped in yakkety, and I am
unaware of any outstanding regressions. There was some initial fallout then
for d-i and maas-images, which generate uImages on their own, but those
have been resolved within those projects.
