[UBUNTU] Enable NX in all Secure Boot variants and drop strictnx variant This basically removed the build flag: --pcd PcdUninstallMemAttrProtocol=TRUE There is a related bus reports: - https://github.com/flatcar/Flatcar/issues/1821 - https://github.com/tianocore/edk2/issues/10918 where it has been stated: "Another known issue is that there are broken grub versions which get things wrong in case EFI_MEMORY_ATTRIBUTE_PROTOCOL is present. edk2 enabled this on on x64 end of last year so it is present in 2025-02 + newer." ** Bug watch added: github.com/flatcar/Flatcar/issues #1821 https://github.com/flatcar/Flatcar/issues/1821 ** Bug watch added: github.com/tianocore/edk2/issues #10918 https://github.com/tianocore/edk2/issues/10918 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2147205 Title: ovmf crashes when used with qemu and an emulated TPM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/2147205/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
