Re: [Ltsp-discuss] Client boot error: piix4_smbus ... Host SMBus controller not enabled
Addendum: Even though I reference Lubuntu 12.04, I find that the behavior is exactly the same under Edubuntu 12.04.

I think that the error reports refer to the state of the eMachines PC, since another LTSP client does not generate the error.
