Bug Description
While running a compile on my laptop, I suddenly got a console message that the system was shutting down for poweroff because the critical temperature had been reached. I expected that, when the warning threshold was reached, the cpu frequency would be lowered to avoid overheating; this doesn't appear to be what happened.
Assigning this to the kernel since AFAIK cpu frequency is now handled by default entirely in the kernel through the ondemand governor, so this doesn't seem to be a userspace policy problem.
