Issue #524 has been reported by Paul Menzel.
---------------------------------------- Bug #524: `CONFIG_X2APIC_ONLY=y`or `CONFIG_X2APIC_RUNTIME=y` cause Linux in emulation/qemu-i440fx to crash https://ticket.coreboot.org/issues/524
* Author: Paul Menzel * Status: New * Priority: Normal * Target version: none * Start date: 2024-02-04 * Affected versions: 4.21 ---------------------------------------- Build coreboot for `emulation/qemu-i440fx` with `CONFIG_X2APIC_ONLY=y`or `CONFIG_X2APIC_RUNTIME=y` causes Linux to crash:
### `CONFIG_X2APIC_ONLY=y`
``` $ qemu-system-x86_64 -bios /dev/shm/coreboot/build/coreboot.rom -L /dev/shm -enable-kvm -smp cpus=2 -m 1G -hda /dev/shm/debian-32.img -serial stdio -net nic -net user,hostfwd=tcp::22222-:22 WARNING: Image format was not specified for '/dev/shm/debian-32.img' and probing guessed raw. Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted. Specify the 'raw' format explicitly to remove the restrictions.
