How do interrupts work under a dual-core DOS system? Is it possible that interrupts can't run normally? One of my serial port service programs doesn't run properly on a dual-core system and tends to lose data easily, which means the interrupts can't respond completely, but it runs normally on a single-core system. I don't know what's going on.

If I remember right, under SMP interrupt handling is managed by the APIC (Advanced Programmable Interrupt Controller).
I don't know the specific details; you can check the Intel documentation |
