Upgraded to 13.1, and it is very slow. Almost always stuck at 800MHz, and *almost* unusable. The transition latency value might have something to do with it, but note that 'ondemand' is no longer available for some reason. Setting to 'performance' works (until the next boot). linux-k1fq:/sys/devices/system/cpu/cpu0/cpufreq # for i in *; do echo -n "$i - "; cat $i; done affected_cpus - 0 cpuinfo_cur_freq - 882000 cpuinfo_max_freq - 2100000 cpuinfo_min_freq - 800000 cpuinfo_transition_latency - 4294967295 related_cpus - 0 scaling_available_governors - performance powersave scaling_driver - intel_pstate scaling_governor - powersave scaling_max_freq - 2100000 scaling_min_freq - 800000 scaling_setspeed - <unsupported> linux-k1fq:/sys/devices/system/cpu/cpu0/cpufreq # Reproducible: Always Steps to Reproduce: 1. 2. 3. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
