+ [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.

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.

happy to attach additional logs.
