Bug Description
All of a sudden, the fan has begun spinning most of the time. It will spin up, sometimes spin up / down for a little while, and then it will simply stay on. This happens even if I put the laptop to sleep, and can happen when I have no applications open and top reports low usage. Sometimes (as while I was typing this message!) it will turn off for about a minute, then turn right back on at full speed. No messages in dmesg suggest anything odd, and sensors reports roughly 49-60 C. (Critical is 105.0 and high is 87.0, it says.) Note that often the fan will spin up or down without a corresponding change in the output of sensors.
Is there any way I can diagnose this? The sudden change in behavior makes me think it must have been something in a recent package update. The same upgrade brought with it non-functioning brightness keys.
Since the problems started, I've ensured that the Sputnik PPAs are in my apt list, and I'm now running "3.2.0-39-generic #62+kamal15~
Can you run "apport-collect 1161820" on your system so that we have more details about it for debugging?
