On the notebook computer, parts become very hot to the touch while running Ubuntu, but the fan does not run even after it gets hot. When I boot back to OS X, the fan kicks in and runs until the computer returns to being cool to the touch. Similar for the desktop, though I must follow the temperature with /usr/bin/sensors. The notebook is a MacBookPro8,2 and the desktop is a Macmini3,1 What metrics do I need to collect to help fix the problem? I've already reported the problem to Ubuntu[2] and the recommendation was to try reporting upstream. Please CC me in the replies. /Lars [1] http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ [2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/881593
