[   17.196676] EDAC amd64: This node reports that Memory ECC is currently disabled.
[   17.196679] EDAC amd64: bit 0x400000 in register F3x44 of the MISC_CONTROL device (0000:00:18.3) should be enabled
[   17.196682] EDAC amd64: WARNING: ECC is NOT currently enabled by the BIOS. Module will NOT be loaded.
[   17.196683]     Either Enable ECC in the BIOS, or use the 'ecc_enable_override' parameter.
[   17.196684]     Might be a BIOS bug, if BIOS says ECC is enabled
[   17.196685]     Use of the override can cause unknown side effects.
