X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list Reply-To: Daniel Eischen List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 15 Jan 2008 03:12:01 -0000 The man pages don't appear to be very helpful. How do I disable ACPI thermal from shutting down my machine when it incorrectly is detecting false temperature readings? Do I have to disable ACPI altogether? Can I safely kill the acpi_thermal thread? Thermal zone 0 skyrockets past 110C in a couple of minutes when trying to build a kernel. All the other zones stay relatively static. I suspect something is wrong somewhere because this machine is very lightly loaded and has never had a problem until now. I just upgraded it from 4.x to 7.0.
