Bug Description

I am currently building my own kernel with bootloader and qemu crashed after I have set an IDT in protected mode and then create a invalid opcode exception with the opcode 0xff.

My code is here: https://github.com/Luis-Hebendanz/svm_kernel/blob/qemu_crash/svm_kernel/external/bootloader/src/main.rs#L80

Build instructions are here: https://github.com/Luis-Hebendanz/svm_kernel/tree/qemu_crash

A precompiled binary is here: https://cloud.gchq.icu/s/LcjoDWRW2CbxJ5i

I executed the following command: qemu-system-x86_64 -smp cores=4 -cdrom target/x86_64-os/debug/bootimage-svm_kernel.iso -serial stdio -display none -m 4G

I am running QEMU emulator version 5.1.0
