Normally that message is printed only when a key other than ctrl-c is hit 
during the dump.  It's certainly possible to rate-limit the message, or just 
limit it to printing once, but the more interesting question is why the kernel 
thinks a key is (effectively) held down such that it needs to print 
repeatedly.  Could you tell us a bit more about your configuration -- ps/2 / 
usb / serial console?  Mouse of some sort?  Virtual machine or real machine? 
Any other problems with keyboards during normal operation?  Any chance a key 
is being held down?
