From 9136d7422a6b53c50a920f3dd2539bf7fcd4fdf5 Mon Sep 17 00:00:00 2001 From: Seiichi Ikarashi Date: Fri, 12 Jun 2015 06:35:37 -0300 Subject: [PATCH 4/5] rasdaemon: use MCA error msg as error_msg In the case of machine-checks which do not have a model-specific MCA error code but have an architectural code only, mce_event.error_msg becomes empty then you don't know what happened.
