Does the fallback boot entry work?

Have you tried reinstalling the kernel?

I wish arch would (like other distros) keep 2 or three old kernel
versions around because it doesn't take any space to do so
and works around boot bugs in new kernels.

If this is a regression you will have to post dmesg. If you don't see
errors/warnings, then kernel developers would usually ask to enable
debug flags for printing more information during boot.

That said, I have one old machine with a Core2Duo and GM4xx and
ever since DRM's atomic modesetting was introduced in 4.2, I can
only use 4.1 warning free. Regressions do happen but you had no
warnings or errors in 4.8 so yours looks like a different regression.
