The issue here is buried in history
The IBM pc (1982) had 8 interrupts using an 8259 chip. By
putting another 8259 into one of the interrupts they got 15. Thus things
stood for a long time.
Recently there's another 8 added (in some corner of an fpga), but the
hardware doesn't know about them. And this interrupt sharing has also
cocked up things in a lot of places.
t's the issue.
