From f9fc049ef1e05da3e3d2a45d098ec89b89bf687e Mon Sep 17 00:00:00 2001 From: Gary R Hook Date: Wed, 20 Dec 2017 09:47:07 -0700 Subject: iommu/amd - Record more information about unknown events When an unknown type event occurs, the default information written to the syslog should dump raw event data.
