Bug description:
The edac_amd64 module attempts to load on many systems. If the system doesn't have ECC
memory, or it is disabled in the BIOS, then the module prints

EDAC amd64: WARNING: ECC is NOT currently enabled by the BIOS. Module will NOT be loaded.
    Either Enable ECC in the BIOS, or use the 'ecc_enable_override' parameter.
    Might be a BIOS bug, if BIOS says ECC is enabled
    Use of the override can cause unknown side effects.

before failing to load. This won't cause issues for most people that see the message.

kerneloops picks this up as kernel problem as the "WARNING:" looks a lot like what
you get when using WARN().

There are several aspects to this issue:

  * linux
     - something attempts to load the module when perhaps it doesn't need to (unclear at this point)
     - the module looks like it is using WARN() when it isn't, and is arguably more SHOUTY than
       it needs to be.
  * kerneloops
     - picks up this as WARN() when it isn't.
     - Was accidentally left enabled for the stable release, people shouldn't be getting asked to report
        this at this point.
     - Isn't very good at dealing with repeat issues, causing more reports to be sent than are needed.

and possibly others as well.
