Hi, We are using a Lanner FW-7550 running pfSense (FreeBSD 6.2). Yesterday morning the system halted with the error Message from syslogd@mettle-se at Tue Nov 6 10:13:45 2007 ... mettle-se root: WARNING: system temperature too high, shutting down soon! Sysctl values are: # sysctl hw.acpi.thermal.tz0 hw.acpi.thermal.tz0.temperature: 51.0C hw.acpi.thermal.tz0.active: -1 hw.acpi.thermal.tz0.passive_cooling: 1 hw.acpi.thermal.tz0.thermal_flags: 0 hw.acpi.thermal.tz0._PSV: 60.0C hw.acpi.thermal.tz0._HOT: -1 hw.acpi.thermal.tz0._CRT: 60.0C hw.acpi.thermal.tz0._ACx: 60.0C -1 -1 -1 -1 -1 -1 -1 -1 -1 It seems the temperature is climbing till 60C and causing the system to reboot. I checked with manufacturer and they say the system is certified till 70C. When I tried to raise the value of PSV, HOT and CRT to 70, I get an error. # sysctl hw.acpi.thermal.tz0._CRT=70 hw.acpi.thermal.tz0._CRT: 60.0C sysctl: hw.acpi.thermal.tz0._CRT: Operation not permitted I have posted the asl file at http://pastebin.ca/764590 if that helps. with regards, raj
