I've installed 2.6.32-41-generic and replaced the fan on the motherboard, and performance has returned to normal. I've moved the CPU back to on-demand and scaling seems to be working again.
So if someone else has an old laptop and all signs point to the CPU playing up... it might be the fan, (though if, like me, you spend all of your time with headphones on you might not notice the fan stop.) alexx -- "I'm not doing nothing; I'm actively waiting for the problem to go away." -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/951673 Title: CPU Frequency Scaling broken ?
