Public bug reported:
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 sleeping 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 sleep when it's too hot.
(The problem has remained the same from at least Ubuntu 11.10 through
14.04)
