Hello There,

I am using 12.04.2 LTS, and I keep getting this error on console "COULD NOT SET SOC VOLTAGE BACK!!!!", it is flooding the logs.

Any idea what it is, and how to stop?

An unfortunate "bug" in the kernel. It is not dangerous, just someone at freescale making unexpected behaviour sound worse than it is.

Try changing the scaling governor, that usually makes it quiet:

Code: Select all

echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
