The underlying fix must go to 8.4, as it is the third similar problem with "ethtool -e %DEV" that breaks stability of the underlying system. Sos report tool cant afford such its own behaviour due to an issue of a tool invoked.. I tested it manually on RHEL-8.4 x86_64 OLD # rpm -qa sos sos-4.0-5.el8.noarch # sos report --list-plugins | grep 'networking\.' networking.traceroute off collect a traceroute to www.example.com networking.namespace_pattern Specific namespaces pattern to be collected, namespaces pattern should be separated by whitespace as for example "eth* ens2" networking.namespaces 0 Number of namespaces to collect, 0 for unlimited. Incompatible with the namespace_pattern plugin option networking.ethtool_namespaces on Define if ethtool commands should be collected for namespaces Default sos report run # sos report -o networking --batch ... Your sosreport has been generated and saved in: /var/tmp/sosreport-localhost-2021-01-27-kihdqsq.tar.xz # tar tf /var/tmp/sosreport-localhost-2021-01-27-kihdqsq.tar.xz | grep ethtool_-e sosreport-localhost-2021-01-27-kihdqsq/sos_commands/networking/ethtool_-e_lo sosreport-localhost-2021-01-27-kihdqsq/sos_commands/networking/ethtool_-e_eth0 +--------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ NEW # rpm -qa sos sos-4.0-6.el8.noarch We can see that eepromdump is now ignored by default # sos report --list-plugins | grep 'networking\.' networking.traceroute off collect a traceroute to www.example.com networking.namespace_pattern Specific namespaces pattern to be collected, namespaces pattern should be separated by whitespace as for example "eth* ens2" networking.namespaces 0 Number of namespaces to collect, 0 for unlimited.

No official errata planned for 8.1. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
