If its not too much to ask, can you give me any > hints/tips to debug it ? Let's try. First, can you tell us why you needed to backport lm78.c? I don't get it. The w83627ehf driver is standalone and certainly doesn't need lm78 is any way. Second, please don't use gkrellm for testing, as this program is not supported by us. Please use the files in /sys/bus/i2c/devices directly, using "cat" and "echo". At least we will know which action precisely did cause the problem. Third, please enable as much i2c debugging as possible. This can be done in the I2C menu with make menuconfig. also Add #define DEBUG 1 at the top of the w83627ehf.c file. This should let us gather some information. Also, if you had to change something to the w83627ehf file when backporting it, please tell us what exactly you did. If you could share the exact file you are using, it will help us help you. -- Jean Delvare
