I can confirm this bug does exist. Attempting to boot on my Surface Pro 4 requires secure boot to be momentarily shut-off. SB actually is reporting a secure boot violation for whatever reason. I have reason to believe that the UEFI files are missing correct signing, or that signing needs to be updated. I have also seen SB failures with my Dell laptop with SB enabled, but those are easier to work around than going nuclear on a Surface Pro and shutting-off secure boot. F31 and F32 are unaffected, this appears to have started with F33. -- Erich Eickmeyer Project Leader Ubuntu Studio Maintainer Fedora Jam
