It worked: via grub booted 5.8 and no more errors at boot. However, brightness setting is not persistent after a reboot anymore, screen is at max brightness after each reboot. If I modify it using the keyboard, it immediately starts at the lowest brightness.
It's a minor issue. Not a big deal. I will stay away from 5.8.5 for now.
