Well, that's definitely on you. Arch do warn people to actually read the changelogs if you're going to update/upgrade everything. Whenever I've hit a problem with an Arch machine (I think it's only twice), it was written quite clearly in the update notes along with the fix.

It's actually surprising just how stable Arch Linux can be considering that it's typically using the newest code for everything. If you really want Arch and stability, maybe using something like SteamOS would be better - Arch, but designed to be stable.
