Public bug reported:

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.

I'm an experienced Linux user but not an experienced bug submitter, so
please let me know if I have failed to provide any necessary info. Am
happy to attach additional logs.
