Revision 2ee27796f298b710992a677a7e4d35c8c588b17e authored by Hans de Goede on 30 December 2018, 17:27:15 UTC, committed by Ingo Molnar on 19 April 2019, 17:23:13 UTC
The "ENERGY_PERF_BIAS: Set to 'normal', was 'performance'" message triggers on pretty much every Intel machine. The purpose of log messages with a warning level is to notify the user of something which potentially is a problem, or at least somewhat unexpected. This message clearly does not match those criteria, so lower its log priority from warning to info.
