Hi,
I'm running a CentOS 2.6.18-164 kernel patched with the ipmisensors patch recommended for >= 2.6.17 versions, to try and retrieve sensor information through an IPMI interface.
Using lm_sensors version 3.1.2:
Sensors-detect locates it as follows:
Found `IPMI BMC KCS' at 0xca2... Success!
(confidence 8, driver `ipmisensors')
However, 'sensors reports 'no sensors found'.
Debugging sensors with gdb, it would appear that no entries are added to the sensors_proc_chips_count through sensors_add_proc_chips from within sensors_read_one_sysfs_chip. This in turn would appear to be a result of the ipmi entry not having a "name" attribute as checked by sysfs_read_attr, under the comment /* ignore any device without name attribute */ in sysfs.c.
ipmisensors, ipmi_si and ipmi_msghandler are all loaded and running.
What I'm not sure if I've missed a step somewhere that would add the name attribute under the hwmon_path for this ipmi interface? Or what that "name" attribute would look like.
Output of sensors-detect, sensors, and dmesg (filtered for ipmi) is attached.
Any help would be appreciated.
thanks,

No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): YES

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): YES
Found `IPMI BMC KCS' at 0xca2... Success!
(confidence 8, driver `ipmisensors')
Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): YES
Found unknown SMBus adapter 8086:3b30 at 0000:00:1f.3.
