Since Linux 4.0 the CPU fan speed is going up and down on Dell Studio XPS 8000 and 8100 for unknown reasons. The 8100 was already blacklisted in commit a4b45b25f18d ("hwmon: (dell-smm) Blacklist Dell Studio XPS 8100"). This patch blacklists the XPS 8000. Without further debugging on the affected machine, it is not possible to find the problem.
