This is a Pentium 2.
OK, I think I see where you're going. Bleeding-edge stuff has some
different kind of interrupt system that breaks the ISA 16-IRQ limit? I
fired up the Athlon and took a look at its /proc/interrupts. Ah, so. I'd
never have thought of looking there.
So, this is a big problem for keeping old warhorses in service for
network infrastructure, but it wouldn't apply to newly designed
purpose-built hardware.
The Opterons and Athlons and such would be too power-hungry for
device servers and firewalls and the like, but presumably there are other
choices that wouldn't be I/O-starved and still take it easy on the power
bill.
