Hi,

this does not appear to be a kernel bug, just a warning about the ECC not being enabled in your BIOS:

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.

You can either see if you can enable ECC in your BIOS (ECC provides single-bit error detection for the system memory) or add the amd64_edac.ecc_enable_override=1 to the kernel boot line.

Let me know if this helps.
