EDAC is designed to report errors in the core system.
These are low-level errors that are reported in the CPU or
supporting chipset or other subsystems:
memory errors, cache errors, PCI errors, thermal throttling, etc..
If unsure, select 'Y'.

If this code is reporting problems on your system, please
see the EDAC project web pages for more information at:

<http://bluesmoke.sourceforge.net/>

and:

<http://buttersideup.com/edacwiki>

There is also a mailing list for the EDAC project, which can
be found via the sourceforge page.
