Your issue is likely triggered by setting radeon.hw_i2c=1. Is it really necessary to get your system working? > The problem is when I start the 'sensors' command from the terminal, a > whole system freeze about 6-7 seconds and then return the output. > This prevents me from using the conky software that uses 'sensors' to read > the temperatures and can not even start the 'watch sensors' command because > it would cause the whole freeze. lm-sensors just parses some file in /sys/class/hwmon, so the bug is actually in the kernel. To identify the faulty kernel module (likely related to radeon), could you please run the following command and send the output to this bug report: strace -tt sensors That will help to better identify the issue.
