Is there a reason why my Dell Optiplex 390 stopped working with the Linux 7 kernel?

I was happily coding along on my Dell Optiplex 390 and then the version 7 kernel hit and then for some reason the terminal emulator I was using on Arch stopped working. I could not get that working. So I moved to Ubuntu thinking that would be more stable.

Then for some reason Ubuntu said the WiFi driver is installed but it just plain refused to work. Then I moved to a Fedora version that still used the 6.18 kernel and then suddenly everything worked again. I did make the mistake of upgrading that to the 7 kernel that refused to load but luckily fedora lets you boot back into the 6.18 kernel even if the version 7 is present on the machine. Which made it possible to use the machine again.

When I try to load to load into the 7 kernel It is just a blank black screen with a blinking underscore in the top left corner.

Am I going to have to wait the 7 kernel out until it gets stable or is my machine hard locked into the 6.18 kernel? It is a gen 2 sandy bridge CPU. It is old, but not that old. It should be running. I don't understand why they had to mess around with driver support of old hardware that was running perfectly well on the old version and break it.

Is this type of teething problems standard for a new major release of Linux? Am I just going to have to use the 6.18 kernel while the 7 kernel becomes mature and all the old bug fixes gets added or am I stuck on the 6.18 kernel?
