[lm-sensors] Supermicro X6DH8-G2+ / sensors not working

Forget about smbus-arp, it's an old experimental module which was never
ported to Linux 2.6 (and never will be.)

You must be using an old version of lm_sensors. Type 8 is DDR2 SDRAM,
which is supported for quite some time now.

Not really helpful, we distribute the file, so we know what's inside,
and this file isn't relevant at this point anyway, as you don't even
have a hardware monitoring driver loaded.

This is quite old, and your hardware is brand new. This just can't work.

This is an old version of sensors-detect, no wonder it doesn't detect
your sensors. Please try again with the version of sensors-detect which
comes with the freshly released lm_sensors 2.10.1.

I think I've seen this motherboard before, so I guess it'll find a
National Semiconductor LM93 for the temperatures and voltages, and a
National Semiconductor PC87427 Super-I/O chip for the fans. Status for
these chips is as follows:

* A driver for the LM93 chip exists but wasn't officially ported to
Linux 2.6. There was a preliminary port posted to this list at the
times of ~ 2.6.10, but it was never properly reviewed due to lack of
time.

* We have a datasheet for the PC87427 but no public driver yet. I've
been working on the fan support though, I have a preliminary driver
waiting for testers.

No idea, sorry. The motherboard maker should tell you.
