Questions re this statement in the ZDNET article --
"In all cases, users reported that downgrading systems to a previous release to reverse the BootHole patches usually fixed their problems."
A previous release of what? GRUB2
So that's my first question.
There are some canonical packages - the combination/grouping is important.

Furthermore the corresponding shim and kernel rpms should be installed together (or the kernel should be reinstalled)

Second. I'm assuming the the muti-screen UEFI settings I see are standard for more recent BIOS -- not sure of version. Do we have any guidance for that?
If it is the case that a downgrade to previous grub2 can fix the problem -- and not latest kernel? Does this matter? -- maybe booting from your chosen "rescue" option AND reinstalling older grub (somehow) can get us further along.
