When ran in Oracle Virtualbox, code runs flawlessly. Code that is detecting the ACPI-Info (with a bit of debug-output): ``` multiboot_memory_map32_t* map = (multiboot_memory_map32_t*)mmap; for (uint32_t i = 0; i < size; i++) { Termutils::cout << map[i].type << "type of block "; if (mmap[i].type == MULTIBOOT_MEMORY_ACPI_RECLAIMABLE) { Termutils::cout << "WE ARE INSIDE\n"; fadt = (FADT*)(map[i].base_addr_low); } if (i % 9 == 0) { Termutils::cout << "\n"; } } ``` command qemu is run with: qemu-img create build/objects/test 500M qemu-system-i386 -hda $(APP_DIR)/clinl.iso -hdb ./build/objects/test The iso-image is (zipped) included as attachment. qemu-system-i386 --version: QEMU emulator version 2.10.1(qemu-2.10.1-3.fc27) Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1767146/+subscriptions
