You shouldn't actually need write permissions to the directory since user-space won't be creating or deleteing files in via686a-isa-6000... And all the individual files have the right permisions... David, what OS are you running on? I had a similar problem on SuSE Linux 8 for 64-bit Opteron that was caused by sensors_proc_write having it's data violated by some other code... Can you run 'strace -o sensors.strace sensors -s' and post the last 20 or 30 lines of the sensors.strace file?. I'm looking for pairs of calls to sysctl where the first works and the second has a strange (???) entry in the first argument to sysctl. If so, I've got a patch that you can try... :v) Mark D.
