In reference to ticket #1647 I found that the sensors binary was looking for temp1_hyst, but in the source temp_hyst is referenced for LM75. Here are the changes I made to make it work. ------------------------------------------------------------------------ ------------------ diff -cbr lm_sensors-2.8.6/doc/chips/lm75 lm_sensors-2.8.6-patch/doc/chips/lm75 *** lm_sensors-2.8.6/doc/chips/lm75 2002-09-12 19:20:32.000000000 -0600 --- lm_sensors-2.8.6-patch/doc/chips/lm75 2004-04-08 10:29:00.000000000 -0600 *************** *** 87,98 **** Chip `lm75' LABEL LABEL CLASS COMPUTE CLASS ACCESS MAGNITUDE temp NONE NONE R 1 !
