Interrupt-sharing should not be a problem. PCI is designed to handle
shared interrupts after all.  (That being said, there do exist cards
and drivers that do not handle shared interrupts very well, but that
is very much the exception rather than the rule.)

If there was some dirt or something that caused one or more of the pins
on the card from making proper contact with the slot, then that
could indeed have caused the problems you saw.
