I use the latest LTS, just like AlpineLinux. And it all worked until a few versions back? (I mean, it is not something "terrible", i just thought i report the proble= m, because it is a "detoriation of state" that lasts for now several kernel updates.) lscpu nonetheless and in short is Vendor ID: AuthenticAMD Model name: AMD Ryzen 5 220 w/ Radeon 740M Graphics CPU family: 25 Model: 124 Thread(s) per core: 1 Core(s) per socket: 6 Socket(s): 1 Stepping: 0 Microcode version: 0xa70c00a Frequency boost: enabled CPU(s) scaling MHz: 39% CPU max MHz: 3201.0000 CPU min MHz: 406.4770 CPU(s): 12 On-line CPU(s) list: 0-10:2 Off-line CPU(s) list: 1-11:2 # bin/cpupower.sh CPU 0: freq: 406477-3201000; scaling: 406477-640200; boost:0; gov: powersave (performance powersave); energy: performance (default performance balance_performance balance_power power custom) CPU 2: freq: 406477-3201000; scaling: 406477-640200; boost:0; gov: powersave (performance powersave); energy: performance (default performance balance_performance balance_power power custom) CPU 4: freq: 406477-3201000; scaling: 406477-640200; boost:0; gov: powersave (performance powersave); energy: performance (default performance balance_performance balance_power power custom) CPU 6: freq: 406477-3201000; scaling: 406477-640200; boost:0; gov: powersave (performance powersave); energy: performance (default performance balance_performance balance_power power custom) CPU 8: freq: 406477-3201000; scaling: 406477-640200; boost:0; gov: powersave (performance powersave); energy: performance (default performance balance_performance balance_power power custom) CPU 10: freq: 406477-3201000; scaling: 406477-640200; boost:0; gov: powersa= ve (performance powersave); energy: performance (default performance balance_performance balance_power power custom) P- (energy "should" be "power" in this state, and was until a few weeks ago.) --=20 You may reply to this email to add a comment.
