Looks like the card's interrupt didn't clear. Either its firing more  
interrupts than the CPU can handle ( not too likely ) or the card's  
driver fails to clear it for some reason.
Or the paranoia code is running amok but since it never did that  
before it's still likely triggered by the ISDN card or its driver.

have fun
