I was about to post a support ticket but saw that I ought to post here instead whilst the system is down. I'm running Debian/Etch with a 2.6.15-1-686 kernel. The I think the system is a Dell Optiplex GX280 which from reading Dell's website gives me an Intel 915G chipset (if I've correctly identified the system!). Running sensors detect gave me the following to add to my modules.conf. #----cut here---- # I2C adapter drivers i2c-i801 # I2C chip drivers eeprom #----cut here---- I've loaded these modules Looking through the output of lsmod I get: cressida:/home/james# lsmod | grep i2c i2c_dev 8640 0 i2c_i801 7916 0 i2c_core 19280 3 eeprom,i2c_dev,i2c_i801 sysfs appears to be correctly mounted: cressida:/home/james# mount | grep sys sysfs on /sys type sysfs (rw) But when I run sensors I get the following output: cressida:/home/james# sensors Can't access procfs/sysfs file Unable to find i2c bus information; For 2.6 kernels, make sure you have mounted sysfs and libsensors was compiled with sysfs support! For older kernels, make sure you have done 'modprobe i2c-proc'! cressida:/home/james# Any idea what I'm doing wrong? :( Many thanks, James
