** Description changed:
+ == SRU Justification Bionic/Disco ==
+
+ proc_thermal messages are spamming the kernel log when used in
+ conjunction with thermal. This is because the message is not set at the
+ correct kernel log level.
+
+ == Fix ==
+
+ Upstream fix 44c0c23725a16c8803b8809b87651405e8741e4d ("drivers:
+ thermal: processor_thermal: Downgrade error message"). This is in 5.2 so
+ not applicable for Eoan.
+
+ This fix needs a minor backport wiggle for Bionic because the driver is
+ located in a different place.
+
+ == Test case ==
+
+ Without the fix the kernel log is being spammed periodically with
+ messages in the form:
+
+ [ 11.520358] proc_thermal 0000:00:00.1: Unsupported event [0x91]
+ [ 16.532358] proc_thermal 0000:00:00.1: Unsupported event [0x91]
+ [ 21.572719] proc_thermal 0000:00:00.1: Unsupported event [0x91]
+ [ 26.580855] proc_thermal 0000:00:00.1: Unsupported event [0x91]
+
+ With the fix these messages are no longer appearing.
+
+ == Regression Potential ==
+
+ This changes the log level, so regression potential is very limited,
+ unless some program is relying on this message for some particular
+ reason.
+
+
