All the thread connected with this issue is described here https://www.spinics.net/lists/linux-edac/msg08170.html. Commit 24281a2f4ca569d44e44e4cbc500cf08e7bb4c36 is in mailine as of v4.15-rc1. == Fix == commit 24281a2f4ca569d44e44e4cbc500cf08e7bb4c36 Author: Luis Felipe Sandoval Castro Date: Thu Sep 28 08:54:42 2017 -0500 EDAC, sb_edac: Fix missing DIMM sysfs entries with KNL SNC2/SNC4 mode == Regression Potential == Low. Limited to EDAC checking dimm capacity. == Test Case == A test kernel was built with this patch and tested by the original bug reporter. The bug reporter states the test kernel resolved the bug.
