From 0ba98ec9196746dd6abfa7bb9856ef4f29ffb9be Mon Sep 17 00:00:00 2001 From: Betty Dall Date: Thu, 6 Jun 2013 12:10:50 -0600 Subject: [PATCH] ACPI / APEI: Force fatal AER severity when component has been reset The CPER error record has a reset bit that indicates that the platform has reset the component. The reset bit can be set for any severity error including recoverable. From the AER code path's perspective, any error is fatal if the component has been reset. This patch upgrades the severity of the AER recovery to AER_FATAL whenever the CPER error record indicates that the component has been reset.
