The loop that reads and deMuxes the IRQ lines for Dino exits after
a few times in order to avoid monopolizing the CPU.
What that msg tells me is we are in the interrupt handler long
enough that the next eth0 interrupt is outstanding again.
I would guess this is because IDE is handling IO on the interrupt
stack (reading block data via PIO).
IDE in PIO Mode (ie not using DMA) does not play well with the
rest of the system.
You can usually ignore this msg.

Nope. IDE is EEEeevil ;^)
