The error is caused by the following combination of options: CONFIG_I2C=m CONFIG_I2C_I801=y I can reproduce it even with mainline now. This is caused by CONFIG_ITCO_WDT=y, which selects CONFIG_I2C_I801=y without selecting its dependencies (CONFIG_I2C.) Thanks for reporting, I'll post a fix shortly. -- Jean Delvare SUSE L3 Support
