An SoC's (with the IBECC feature) memory error reporting type is determined. 
Switching from NMI to Machine Check or vice versa for a given SoC is pointless
in the real world.

Additionally, the interrupt mode is preferred over the polling mode unless 
the interrupt cannot work, as in the case you reported.
