Hi Paul,

Thanks! I had this working on 2.8.18.3, and it failed after moving to a
kernel.org 2.6.19.1 kernel -- 

The receipt suggests the daemon starts:

# /etc/init.d/sensord start
Starting sensor daemon: sensord.

But you're right - the syslog shows the failure:

Dec 20 10:36:14 chianti sensord: sensord started
Dec 20 10:36:14 chianti sensord: Chip: k8temp-pci-00c3
Dec 20 10:36:14 chianti sensord: Adapter: PCI adapter
Dec 20 10:36:14 chianti sensord:   Mboard: 31.00
Dec 20 10:36:14 chianti sensord: Error getting sensor data: k8temp/temp2:
Can't access procfs/sysfs file
Dec 20 10:36:14 chianti sensord: sensord failed

It turns out the solution was to add a couple of ignores to the
configuration (previous conf below):

chip "k8temp-*"

   label temp1 "Mboard"
   ignore temp2
   label temp3 "CPU k8"
   ignore temp4

The error messages are not very helpful to newbies -- now I realize
that "Can't access procfs/sysfs file" means "there isn't any temp2 sensors
according to /proc or /sys, so I'm going to fail". A newbie like myself
might think sensors isn't seeing /proc or /sys, or that these file systems
aren't correctly installed, and so on. In any case, the default behavior
shouldn't be to fail because some ignore statements are missing!

Thanks for your help -- that's really all I needed, and hopefully this will
be useful for someone else.

Dave
