Maybe your distribution is loading it by default for everyone then. Either way, it means you can forget right away about sbs, if i2c_ec didn't register a device, sbs cannot be used. > # i2cdetect 0 > WARNING!

So I'd be surprised that i2c-piix4 is causing any trouble. This leaves asus_acpi as the only candidate? Better unload _all_ the drivers you consider as suspects, and see if it changes anything. I guess not. -- Jean Delvare From mboxrd@z Thu Jan 1 00:00:00 1970 From: khali@linux-fr.org (Jean Delvare) Date: Wed, 21 Feb 2007 16:22:07 +0000 Subject: [lm-sensors] Could the k8temp driver be interfering with ACPI?
