Subject: [PATCH 71/76] CPER failed to handle generic error records with multiple sections
Date: Fri, 30 Mar 2012 06:14:14 -0400 [thread overview]
Message-ID: <37d2a3622d249d83413c92a1cd9e94b5237d0fcc.1333101989.git.len.brown@intel.com> (raw)

From: Jiang Liu <liuj97@gmail.com>
The function apei_estatus_print() and apei_estatus_check() forget to move ahead
the gdata pointer when dealing with multiple generic error data sections.
