For an LTSP network where all the clients show this client boot error,
can I
sudo gedit /opt/ltsp/i386/etc/modprobe.d/blacklist.conf
then add
blacklist i2c_piix4
to the blacklist and save,
then
sudo ltsp-build-client --arch i386
to rebuild my LTSP client image?
Is that likely to fix the problem?

P.S. I have been on mail lists where the convention was to reply with
new material at the top of the email, others where they wanted all posts
in plain text (no rich text or HTML), and I think others where they
wanted all posts trimmed of previous material. One person on this list
declared that the accepted practice here was to add new material to the
bottom of the email, following all the older material. Can anyone
confirm or deny?
(As you can see from this email, I've been using the new-stuff-on-top
approach.)

Addendum: Even though I reference Lubuntu 12.04, I find that the
behavior is exactly the same under Edubuntu 12.04.

A refined request:
The research that I have done on this has not shown that this
condition ever did any harm. So instead of asking how to enable the
controller somehow, I would now ask: How can I modify the image being
downloaded to the terminal so that the error does not appear? For
instance, can I blacklist a module in the image?

Hi, all.
Continuing to work through my newbie questions on my first LTSP setup:
After Lubuntu 12.04 has begun booting on an eMachines iTower 500i
client, it generates the error:
/piix4_smbus 0000:00:0.7.3: Host SMBus controller not enabled/
But it continues booting and, so far as I can tell at the moment,
everything works.
When the machine is then shut down or rebooted, a similar message
appears:
/saned disabled; edit /etc/default/saned/
/Host SMBus controller not enabled/
Even if everything works, these are disturbing messages.
Some online posts associate these messages with various things that
don't work, so it may be that I simply have not discovered the
damage yet.
For situations not involving LTSP, a couple sources prescribe adding
/blacklist i2c_piix4/
to /etc/modprobe.d/blacklist.conf
I did this on the LTSP server, but whatever the effect on the
server, it did not solve the problem on the client.
Other sources also recommend upgrading the BIOS to solve this
problem. They note that some BIOS implementations leave the SMBus
controller disabled by default. I did upgrade the BIOS on the
eMachines, but it did not fix the problem, and I did not recognize
any BIOS settings that might allow me to enable the SMBus controller.
I think that the error reports refer to the state of the eMachines
PC, since another LTSP client does not generate the error.
Anyone recognize this problem and have a solution?
