Running 2.2.7 here, I often run into this problem: my serial ports, though detected perfectly by setserial, fail to show interrupts in /proc/interrupts. This happens with my soundcard as well, occasionally (though right now it does have an interrupt - none for the serials though).
This isn't a problem, it's standard behaviour. /proc/interrupts show which interrupts are currently active and registered with the kernel. The serial driver releases the IRQ if there are no ports open using that IRQ. This allows the IRQ to be shared by other devices (normally other serial devices).
