I need help configuring lm_sensors for a SuperMicro H8DG6-F-O motherboard.
I have an interesting challenge... my motherboard is a SuperMicro
H8DG6-F-O motherboard with an IPMI BMC Chipset [1], and I'm trying to
collect fan speed (among other things) via lm-sensors. I've been in
ongoing discussions with SuperMicro, and I need some help - I can get
what I need via the IPMI interface:

I've seen mention that I shouldn't be using the Windbond w83627dhg
sensor, as the temps and fans aren't connected. Is this true, or am I
just missing the correct SMBus offsets?
SuperMicro recommends against installing lm_sensors:
--------------------------------------------------------------------------
SuperMicro: We are not recommend user install lmssenors or any 3th
party sensor monitor utility to monitor sensor reading on motherboard
with IPMI (BMC) chipset. It could cause system to crash due to 2
sensors monitor probing sensor reading in the same time.
Me: So you are saying NOT to install lm-sensors with a BMC-equipped motherboard?
SuperMicro: Yes. Our LAB able the duplicate issue regarding system
crash when installing lm-sensor on motherboard with BMC-equipped
motherboard. System crash could happen in random time.
--------------------------------------------------------------------------
Does that make sense to the list?
Their advice is confusing, since at the same time as they were telling
me to NOT install lm_sensors, they gave me the offsets necessary to
make the WinBond work with lm_sensors:
SuperMicro:
--------------------------------------------------------------------------
Please check the offset address for lm-sensor to match information below.

I found mention of this on the List Archive [2].
I also found the configuration settings for a SuperMicro H8DC8 with a
WinBond W83627HF. [3]
I am unclear about using the WinBond vs IPMI - are they the same (I
think not)? If they're not, should I be using WinBond with this
motherboard, or stick with IPMI? If I should stick with IPMI, there is
no lm_sensor support for the BMC chipset, so what are my options? I
would rather not have to abandon lm_sensors, for any number of reasons
- not least of which is I would then have to roll my own sysstat,
removing all lm_sensor deps.
And finally, I'm confused how to take these offsets and turn them into
a configuration? I'll gladly update the wiki with it when/if I can get
it done...
