On these we run Fedora Core 2 with all available updates through yum. On most of our other servers we have the ability to monitor the cpu temperature through '/proc/acpi/thermal_zone/THRM/temperature' and this works fine. We monitor most servers using rrd graphs. Now, the problem with all these supermicro servers is that the temperature seems to be stuck at 27 C. No matter what load or temperature in the room. Something is clearly wrong. What can be done to fix this? We tried setting polling_frequency to '10', but that made no difference. What can be done to fix this? Btw, lm_sensors finds no chips.

There "acpi -t" was reporting correct temperatures (as lm-sensors). Now with 2.6.7-rc2-mm2 It reports 22C constantly. lm-sensors gives 40-43C. This is on nForce2 MB with Athlon XP2500+ Same .config.
