Intel 82801 SMBus dmesg question

Denny White
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1


Had originally posted a message "Tuning NFS File Transfer Speed"
and had eventually posted a "Solved" reply to it on the list.
That turned out to be erroneous. It did turn out to be a hardware
issue. Had some leaking capacitors on the old VIA Abit mobo and
replaced it with a Aopen MX3ST mobo picked up on the cheap. All
seems to be working okay so far, but my question concerns what
dmesg is saying. I googled all over, searched in the archives,
and came up with lots of dmesg's that mentioned it, but didn't
explain specifically what that one line meant. It says:

"Intel 82801BA SMBus" rev 0x05 at pci0 dev 31 function 3 not configured

Before asking anything on the list, I tried different things in the BIOS
like disabling USB, the onboard NIC, juggled some IRQ's, just generally
doing some experimenting, but the message is still there. I'd just like
to know what exactly it means & maybe be pointed to a site that explains
it so I can learn more about it. Will put in output of dmesg & ifconfig
below. Thanks for all replies.

There's nothing wrong. It just mean SMBus is not supported. SMBus is a
system management bus.  It is generally used to read and control fans,
temperature sensors and such.  It is not supported on 3.8, but 3.9
will support a wide variety of SMBus controllers.

Install 3.9-beta to take a look. It's available on the various
mirrors.  The ichiic(4) and iic(4) man pages contain some more info.
You can read them via the web site:

Thanks, Otto, for the reply. I'll try it. Have an old Prioris server
donated from a friend to experiment on. Just checked in 3.8 and there's
a man page for iic, leading eventually to other related stuff, including
sensorsd and sysctl. I've played around with them a little, especially
when I was having mobo problems. Thanks again.
