[ 3.872387] i2c /dev entries driver [ 3.873943] i801_smbus 0000:00:1f.3: PCI INT B -> GSI 23 (level, low) -> IRQ 23 [ 3.875580] w83627hf: Found W83627HF chip at 0x290 IRQ23 is also used by i801_smbus and it would be nice to confirm whether the problem can still be triggered with that driver not loaded. Adding "blacklist i2c_i801" to /etc/modprobe.d/blacklist should probabaly do the trick. Thanks. -- tejun
