https://bugzilla.kernel.org/show_bug.cgi?id=58001 --- Comment #22 from Paul Johnson <pauljohn@xxxxxx> --- Is it possible that different Intel chips respond differently? I'm running Ubuntu 14.04 on 2 laptops and one has the problem, the other does not. On the Dell Precision m4600 laptop, I had the chronic problem that, after suspend, I was always stuck at 800MHZ. To fix that, I had to explicitly reset the threshold lower. Eventually, I found a script that did it #!/bin/bash ## https://gist.github.com/Pyppe/6028707 # default with 13.04 is 95 SCALING_FILE=/sys/devices/system/cpu/cpufreq/ondemand/up_threshold defvalue=70 if [ ! -f "$SCALING_FILE" ]; then echo "$SCALING_FILE not found" exit 1 fi limit=${1:-$defvalue} if [[ $limit -lt 100 && $limit -gt 30 ]]; then sudo bash -c "echo $limit > $SCALING_FILE" else echo "Invalid value" exit 1 fi However, on a Dell Latitude 6430u, I have no such problem. Frequency scaling works without qualification, before and after suspend. -- You are receiving this mail because: You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
