[Bug 52852] Re: MacBook gets extremely hot under Linux

[Henk Koster]

Same problem here.

I notice that "acpi -V" says: "No support for device type: thermal".
Gnome CPU-Frequency-applet shows 54% (1.0GHz out of 1.83GHz max) for both cores when idling. 

Under similar conditions the OS X frequency is usually 1.5GHz. Yet,
after running Ubuntu for a while the area around the power connector
gets very hot (with or without power connected). When I then quickly
reboot to OS X, the temperature is close to 70C, and then (still in OS
X) slowly dropping to 55-60C.

During this all I never hear a fan (but then my hearing ain't too good).
