[ 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.
