Comment 57 for bug 453444

I wrote a file /etc/rsyslog.d/10-temperature.conf with the following content:

:msg,contains,"Temperature/speed normal" ~
:msg,contains,"Temperature above threshold" ~

All messages containing "Temperature/speed normal" and "Temperature above threshold" are discarded.
I restarted rsyslog and it looks like the problem is solved.

I hope this will help until the problem will be fixed in the kernel.
