My custom build kernel 4.9.327 with gcc-11.2 is not booting in Qemu and it
is stuck on "Booting from ROM".

Just like the screenshot here: Custom 64bit 3.10.9 kernel not booting in
qemu and stucks on Booting from ROM
<https://unix.stackexchange.com/questions/625230/custom-64bit-3-10-9-kernel-not-booting-in-qemu-and-stucks-on-booting-from-rom>

I run qemu-system-x86_64 -kernel linux-4.9.327/arch/x86/boot/bzImage

Shouldn't the kernel crash?

Any tips?
