I installed the packages (needed headers too), rebooted into and selected that version in grub, and so far it is passing my stress test that provokes gpu hangs, and no hang yet, which is great!
Also, I haven't seen the warning yet (the ones I originally reported), but that happens durng normal operation and may never happen during stress. I'll use it normally for a bit and report what happens.
