Yes, if the SMI flood never ends. But you wouldn't want to work on such 
a system anyway (with the current kernel code, your APIC timer would 
most probably be miscalibrated, which can have the weirdest effects).

Anyway, we can add a maximum iteration count to the patch so that there 
is no risk of getting stuck.
