It doesn't matter whether this machine has the common old-age ailment of dried thermal grease or not. It's part of normal ageing, so Linux needs to be able to handle it in a non-destructive way.
Now Linux is being bullheadedly intolerant to common ailments. It's like a doctor letting an old patient suffer from an indefinitely drug- relievable illness and saying "no, you must buy an expensive life- threatening surgery to correct the underlying root cause". (This parable is apt, because in my computer one insert brass nut has popped off the case and is now spinning in its cavity with the screw, so I would have to do something drastic to even reach the thermal grease.) What kind of an attitude is that to the continual improvement of Linux? https://en.wikipedia.org/wiki/Continual_improvement_process Will it ever be smart if you avoid making it smarter? Or have I mistaken about the goal of Linux development? Even my car from 1995 (Nissan) is smarter than this: in the case of overheating, it can protect itself gracefully in many ways; it doesn't kill the engine demanding immediate cooling system repair - it starts doing every possible cooling action and avoiding various heating actions in the order of least annoyance to the user. Then it informs the user about the heat problem, so that they can help. Then it files an error report about having overheated. Quite a lot better than Linux in 2015. The concept of "failing safely" should be applied here. https://en.wikipedia.org/wiki/Fail-safe Users of these ailing (or just dusty) computers are now suffering of abrupt forced shut downs when they could easily be given lesser evils (noisier fan, slower processing, suspending for a bit every once in a while). All the opportunities to remedy the situation should be taken, because as nothing always works, a low number of actions taken will more likely fail in someone's computer. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1491797 Title: Shuts down when supposed to suspend as a reaction to self-caused overheat, session lost Status in linux package in Ubuntu: In Progress Bug description: Error: Kernel foolishly shuts down the computer when it overheats. /var/log/kern.log W500 kernel: [1448.648529] thermal thermal_zone1: critical temperature reached (100 C), shutting down Consequence: Shutting down destroys session in Ubuntu, Gnome, and all applications that can't remember their latest conscious state (most applications). Attempted repair, failed: Laptop has suspending ability, but I can't find the setting for the kernel to make the computer suspend instead of shutting down. Repair suggestions: 1. Persistence of session, so that everything would reappear after the restart. (this would also make updating less disruptive) 2. Do not heat the machine like crazy; speed up fans or slow down processes. (problematic Lenovo Thinkpad W500 fan on low speed right up to the fiery end) 3. Put the computer to suspend when it's too hot.
