This reminds me:  when using the older CSC-T cards, always "shutdown" any
unused interfaces.  I don't recall whether the cisco crashed, or the in-service
links had problems, but issuing the shutdown command on all unused links 
cleared up our problems (this was about a year ago).  I don't recall any 
similar problems with the cisco designed cards (MCI & SCI), but I wasn't 
about to take a chance, so the rule here is "shutdown".
