Hey Andy sounds like you have a heap of fail on your hands. I have had a patch for a few weeks now. Ubuntu's fan speed is too slow, and this is the cause of 99% of the 100 posts on this thread. You probalby can't reproduce the issue because your laptops are not powerful enough. I can't even run VMWare on my intel dual 2.4ghz dell for more than 20 min without speeding up the fan. For me its not a matter of reproducing this, it is a huge barrier that i faced every day until I fixed it. People are really pissed off, and i was one of them.
