Graham Mitchell (graham-grahammitchell) wrote : thermald spamming syslog with sysfs write failed constraint_0_power_limit_uw

This seems somewhat related to https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1543046

For some reason thermald is writing the message "sysfs write failed constraint_0_power_limit_uw" to the syslog every few seconds. However, there's nothing in the kernel log.
