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

[Stefan Daniel Schwarz]

I also noticed my MacBook (Black) getting very hot (much hotter than in
OS X). I recently applied a firmware update which claimed to improve fan
behavior, but so far I didn't notice any difference.

The directories /proc/acpi/fan/ and /proc/acpi/thermal_zone/ are both
empty - so Ubuntu's power management hasn't discovered the fan and
cooling systems!

I'm not sure if the MacBook firmware itself can and will prevent serious
overheating. If it doesn't, couldn't that cause permanent damage to the
device? In that case, this bug should be addressed with higher priority,
it certainly is of highest priority to MacBook users who care for the
safety of their pricy MacBooks!

(About the "sleep not working" comments: Can't comment, but if it
doesn't work, please file another bug since it's not directly related to
the overheating issue.)
