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?
