With all the drivers installed in your System, I am surprised SoftRAID is loading. Big Sur does not like old extensions.
Run System Profiler, Extensions. Sort by "obtained from" and take a look at your extensions and how many are unsigned. Every unsigned and "unknown" extension must be deleted. It is possible there is an interaction there. But that is the starting point.
After removing them, paste this into terminal.com:
sudo kmutil clear-staging
followed by:
sudo kextcache -i /
Lets see if that helps at all. You may need to try a clean install, Big Sur is a bigger change than most realize and if you have not done a clean install for a while now is the time.
