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. kern :info : [ 26.430737] EDAC MC0: Giving out device to module ghes_edac.c controller ghes_edac: DEV ghes (INTERRUPT) kern :info : [ 26.441401] EDAC MC1: Giving out device to module ghes_edac.c controller ghes_edac: DEV ghes (INTERRUPT) kern :info : [ 26.452619] GHES: APEI firmware first mode is enabled by APEI bit and WHEA _OSC. We're working on fixing this properly but the fix is not ready yet. Thanks. -- Regards/Gruss, Boris. SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) --
