Hi, Please CC the lm-sensors list. Well the new version is in Linux kernel 2.6.20. Please try with some more new version of kernel. What motherboard model/manufacturer it is? In the meanwhile please can you try as root: rmmod w83793 modprobe i2c-dev i2cdump 0 0x2f It should dump raw register data of the chip. Thanks, Rudolf maluyao napsal(a): > Hi > > I'm using RHEL 5.3 X86_64.The kernel version is 2.6.18-128.el5.
