Was the realtek really at IRQ 3?

I'm NOT an x86 hacker, and I don't understand the interrupt code there
very well..  Is it possible to have an irq line which is shared
between 2 devices which use different interrupt masks?  If so, what
prevents intr_mux() from being called for a TTY interrupt, and then
calling another driver which shares the line but has a NET mask, even
when NET interrupts are masked?

Does this go away if you remove the serial line driver (sio) from your
kernel?  Can we see a (non verbose) dmesg from this box?
