First, please focus your question in one thread. This avoids that we have to do double work here.
Second, I suggest to not downgrade in this case. Using a previous kernel is something you do to jump over one kernel that causes troubles when released, so a short time thing. And even in this case it should be checked if the kernel you are reverting to has security issues.
So, you should use the blacklist option for now. You can find our “official” workaround for this bug here: Battery charge indicator broken on certain ASUS motherboards, automatic suspend doesn't work
When playing with commands like those in the workaround, especially when you have no other menu entries you can revert to, always have a USB stick or such with a live Fedora system prepared to use it to revert the steps in case of unintended outcomes!
With the commands and information of the steps you can find much more information about these issues with your preferred search engine.
However, I strongly suggest to try it again without blacklisting with each future kernel update! The issue is known and likely to be fixed in the next kernel update or the one after that. Removing the blacklisting is explained in the workaround link as well. Although this module is not critical, I suggest to not keep it disabled for all time. It is one of those that can cause you trouble if you forget about its blacklisting at some point but want to retrieve (or if an application wants to retrieve) information it provides without remembering why it is not provided that.
