What's an IRQ storm?

 

Hi,

I've come across this critical FWTS failure on one system which otherwise looks fine for certification:
FAILED [CRITICAL] KlogDisablingIRQ: Test 1, CRITICAL Kernel message: [ 
12.502739] Disabling IRQ #16
ADVICE: The kernel detected an irq storm. This is most probably an IRQ 
routing bug.

Shall I raise a kernel bug for this and can anyone shed any light on the possible effects of this error/what it means?
Thanks,
