These are attached. I ran a diff on the output of the thermal and cpufreq greps (the '.old' files are from the bad kernel, '.log' from a working one): $ diff cpufreq.log cpufreq.old 13c13 < /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq:2534000 --- > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq:1013600 28c28 < /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq:2534000 --- > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq:1013600 As I noted above, the maximum scaling frequency is super low. That appears to be the only difference here. As for the thermal output: diff thermal.log thermal.old 1c1 < /sys/class/thermal/cooling_device0/cur_state:0 --- > /sys/class/thermal/cooling_device0/cur_state:10 4c4 < /sys/class/thermal/cooling_device1/cur_state:0 --- > /sys/class/thermal/cooling_device1/cur_state:10 9a10,11 > /sys/class/thermal/thermal_zone0/cdev0_trip_point:1 > /sys/class/thermal/thermal_zone0/cdev1_trip_point:1 11,12c13 < /sys/class/thermal/thermal_zone0/passive:0 < /sys/class/thermal/thermal_zone0/temp:42000 --- > /sys/class/thermal/thermal_zone0/temp:39000 14a16,17 > /sys/class/thermal/thermal_zone0/trip_point_1_temp:0 > /sys/class/thermal/thermal_zone0/trip_point_1_type:passive There are quite a few differences, most notably the 4 trip point entries in the bad kernel version that don't even exist in the good one, and as you noted, mark 0C or 1C as the tripping temp. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
