I think this is the problem, see below. > # ll /proc/sys/fs ll /proc/sys/dev/sensors/w83781d-i2c-0-2d would be more interesting. But I guess that the files are there, you can most likely read them and write to those of them which are intended to be. If I'm right, then the explanation and solution are right below. > I checked lm_sensors-2.8.6/doc/lm_sensors-FAQ.html Section 4.20 > regarding Linux 2.4. > > Looks like > - for 2.4, lm-sensors-2.8.4 is expected, > - for 2.6, lm-sensors-2.8.6 is expected ??? Not at all. 2.8.6 if fine for both Linux 2.4 and 2.6. Does our FAQ really state the contrary? So, as mentionned below, I suspect that the Gentoo kernel is the problem. I think I remember that there are additional patches in them (grsec and acl among others) which are preventing libsensors from working. We never could understand why, and since these patches are not into the mainline we are not particularly motivated on investigating. If someone provides a solution, we'll gladly consider implementing it however. So I suggest that you try the same operation with a vanilla kernel instead of a Gentoo-patched one and see if it helps. -- Jean Delvare http://khali.linux-fr.org/
