They are not used by I4B (you can toggle them on/off by software, but
Hellmuth didn't find a good reason to do so).

This message is harmless. It means the interrupt handler was called but
found nothing to do. There are a few (more or less) legitimate reasons why
this will happen, and I think this WARNING: has to be removed from I4B.
Think of two PCI cards sharing the same interrupt...

No interrupts were lost, you would see more severe error messages from I4B
in that case. Everything is fine. The ELSA cards are known to cause a
regular interrupt load "by design" (a feature to help their Windows
drivers). There is a hardware modification to shut these (not needed by I4B)
interrupts up, but probably noone ever bothered with this (even a 486 can
easily take that interrupts without causing too much system load).
