If you know, please let me know easy way to realize the bug
concerning to the interrupt? I want to try, because I could
not remember when I found such crashing.

However I'm testing Fiasco on old 486 PC and the ethernet card
is 3c507 on ISA. I'm afraid that the ether device is too poor
to overload the IRQ handler...
