edk2 (2025.02-5) unstable; urgency=medium The EFI_MEMORY_ATTRIBUTE_PROTOCOL is now enabled by default in the OVMF32_CODE_4M.secboot.fd image. This is a security feature that will cause crashes for operating systems with bootloaders that do not observe proper memory access semantics. Users that experience issues with such bootloaders have the options to either append the following to the qemu-system-i386 command line: -fw_cfg name=opt/org.tianocore/UninstallMemAttrProtocol,string=y or switch to the OVMF32_CODE_4M.fd (non-secboot) image, which uninstalls this protocol by default. -- dann frazier Fri, 28 Mar 2025 08:23:47 -0600
