Bug Description
[SRU REQUEST, Xenial, Yakkety]
Thermald is spamming the log with error messages on sysfs write failure messages. Demote these to debug level errors so that they aren't logged unless running in debug mode.
[FIX]
See comment #24, with the fix the messages are not logged when in normal non-debug running mode.
[REGRESSION POTENIAL]
Minimal, this just reduces the logging spam by turning messages into debug only for when running in debug mode.

This seems somewhat related to https:/
For some reason thermald is writing the message "sysfs write failed constraint_

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.

@Graham,
I'm interested in seeing all the kernel log messages as that may give a hint on why this is happening. Can you attach it to the bug report?
I suspect you may also be getting the kernel reporting "powercap intel-rapl:0: package locked by BIOS, monitoring only"
