Kdump Might Fail on Some AMD Hardware

Kdump might fail on some AMD hardware that's running the current Oracle Linux release. Impacted hardware includes the AMD EPYC CPU servers.

To work around this issue, modify the /etc/sysconfig/kdump configuration file and remove the iommu=off command line option from the KDUMP_COMMANDLINE_APPEND variable. Restart the kdump service for the changes to take effect.
