i keep getting this every 3rd boot or so since i built my x570/3800x system last weekend. any idea what to do about it? ive never encountered kernel panic before in my life

Had twice in a lifetime...the one I barely remember was fixed with a convoluted bios setting. A recent one was when I installed incompatible memory sticks. Reading on google it's mostly hardware (likely with your new new rig). Also have read it connected with proprietary drivers. Like viyoriya alluded to, do a half hour of reading and see what situation fits best---in other words AFAIK no one thing causes kernel panic..
edit: I'm not smart enough to decipher the clues in your picture, but someone will.
