Hi David, >I have recently noticed that one of the fans on a box I am monitoring is >no longer sending a tachometer signal, so sensors(1) indicates the >RPM=0. This is as you would expect.

This indicates to me that maybe the part doesn't >think there's a problem?? I would say so. Alarms are reported as generated by the hardware, the sensors program doesn't compute them. However, this could also be caused by a software bug, or maybe there is a way to reconfigure the chip (sometimes alarms are individually maskable). I'll take a look at the datasheet again when I am back home in the evening. In the meantime, could you please: 1* Tell us which version of lm_sensors you are using, with which Linux kernel. 2* Provide a dump of the chip (isadump -f 0x0680 0x80). -- Jean Delvare
