Comment 3 for bug 2070151

The lowlatency kernel isn't supported on the Pi, and flash-kernel won't permit it to be flashed (because you'd be left with an unbootable system).

Ideally the studio installer should detect this and not select the option by default (or better still, disable it), but I'm not sure there's a simple way for them to do that (at least "properly"; it's fairly easy to detect if you're on a Pi, but ideally the installer should be checking the flash-kernel database to see if there's a kernel-flavor limit in place and act accordingly).

I need to have a think about this -- I'm reasonably confident this is a studio installer bug too (so I'll add that as affected), but I suspect flash-kernel needs to grow some facility for exposing the kernel-flavor limits imposed on the running system.
