[root at tb303 ~]# sensors Can't access procfs/sysfs file Kernel interface access error For 2.6 kernels, make sure you have mounted sysfs and libsensors was compiled with sysfs support! I have Debian 4.0 with 2.10.1-3 lm-sensors and libsensors3. I read http://www.lm-sensors.org/wiki/Kernel2.6 "In kernel 2.6.22, the way the I2C adapters are presented in sysfs changed, and this affects libsensors. You will need lm_sensors version 2.10.3 or later. Alternatively, the kernel can be compiled with CONFIG_SYSFS_DEPRECATED=y, then version 2.10.2 will work too. Older versions of lm_sensors will complain that the I2C adapter names can't be read. This is only a warning though. " So in my kernel 2.6.26.5 I have # grep CONFIG_SYSFS_DEPRECATED /boot/config-2.6.26.5 CONFIG_SYSFS_DEPRECATED=y CONFIG_SYSFS_DEPRECATED_V2=y yet I still get this "warning" If it's only a warning why don't I get the actual readings from my hardware? I looked into upgrading to lm-sensors 3 and libsenseors4 packages from Debian testing tree but the dependencies were pretty bad, I might as well upgrade the whole system to testing. I have run sensors-detect and have the proper modules loaded. John Brier
