Hi all, One thing confused me. The disconnect_bsp_APIC() may restore the interrupt delivery mode into virtual wire mode. it uses the vector F as the spurious interrput, But, IMO, using the vector 0xFF(SPURIOUS_APIC_VECTOR) may more suitable and will give us more detail. Why the

[PATCH v3 0/5] x86/apic: Fix restoring boot irq mode in reboot and kexec/kdump

A regression bug was introduced in below commit. commit 522e66464467 ("x86/apic: Disable I/O APIC before shutdown of the local APIC") It caused the action to fail which we try to restore boot irq mode in reboot and kexec/kdump. Details can be seen in patch 0002. Warning can always be seen
