I recently committed a major reworking of the embedded controller driver. See this message: http://lists.freebsd.org/pipermail/freebsd-current/2007-February/069525.html See this message for a list of things to try. The goal is to diagnose why the EC is timing out. The thermal misdetection is only a symptom. http://lists.freebsd.org/pipermail/freebsd-current/2007-February/069577.html The one I think would be most helpful is increasing the total time spent waiting, but I would appreciate your help seeing what combo of polling/total timeout works for you. debug.acpi.ec.timeout=1000 # 1 sec total Thanks, -- Nate
