I guess these were left > out before, but should they be included? I don't think so, since from what I can tell from the Intel SDM (Memory Controller and Extended Memory Errors), extended memory errors use the same encoding as normal memory errors, but report errors in memory that is used as a cache, similar to what cache hierarchy errors do. I also found this thread, where Tony made the same point: https://lore.kernel.org/all/SJ1PR11MB60831E048B544C83E845D907FC8DA@SJ1PR11M= B6083.namprd11.prod.outlook.com/ Best, Adrian
