AFAIR, we talked about this already. You need to disable CONFIG_EDAC_GHES
temporarily as it registers before the sbridge module.
kern :info : [ 26.382523] ghes_edac: This EDAC driver relies on BIOS to enumerate memory and get error reports.
kern :info : [ 26.392439] ghes_edac: Unfortunately, not all BIOSes reflect the memory layout correctly.
kern :info : [ 26.401574] ghes_edac: So, the end result of using this driver varies from vendor to vendor.
kern :info : [ 26.411001] ghes_edac: If you find incorrect reports, please contact your hardware vendor
kern :info : [ 26.420137] ghes_edac: to correct its BIOS.
kern :info : [ 26.424812] ghes_edac: This system has 8 DIMM sockets.

We're working on fixing this properly but the fix is not ready yet.
