Btw, what is exactly the problem with EDAC being enabled and not being
able to suspend? Is it a hardware issue?

Because if it is sw one, we probably could change the EDAC core to
accomodate power management. On x86 we don't need to do anything special
to EDAC wrt PM though - we simply suspend.

Thanks.
