I think you need DM_NMI for that to work correctly.

An alternative is to call the NMI handler directly.
apic_send_IPI_self() already took care of APIC_DM_NMI.

So it does (though not for x2apic?).  I don't see why it doesn't work.

And NMI handler would block the following NMI?


It wouldn't - won't work without extensive changes.
