As of right now, none of the currently supported kernels (4.4.184, 4.9.184, 4.14.131, 4.19.56, and 5.1.15) have any issues with the particular AMD CPU on the system that originally exhibited the problem. The newer kernels all report significantly fewer power states, and the ondemand governor can now be enabled without issue. -- You are receiving this mail because: You are the assignee for the bug. ^ permalink raw reply [flat|nested] 2+ messages in thread
