https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234733 --- Comment #13 from Conrad Meyer <cem@freebsd.org> --- Note that there are several newer BIOSes available for that board: https://www.asrock.com/mb/AMD/B450%20Pro4/#BIOS The only remark that really jumps out is for 3.31, "Change AMD PBO rule with Pinnacle CPU." PBO is "precision boost overdrive" and is something involvi= ng power; Pinnacle is the ryzen 2xxx family. That said, I'd just skip straigh= t to 3.90 as long as you're taking the time to flash a new BIOS. --=20 You are receiving this mail because: You are the assignee for the bug.=
