# first bad commit: [1c4dfadb4611ef511816dfdfbdb37d7d100b5a4b] ArmPkg/CpuDxe: Implement EFI memory attributes protocol
Reverting that from latest upstream seems to make the problem go away. But the reason is not clear to me. This commit registers a protocol, but it doesn't appear to use that protocol on its own. I wonder if the AlmaLinux bootloader stack is trying to use it?
