As probably expected this patch causes problems. In my case one server can no longer load the nct6775 hwmon module, which means the fan cannot be monitored, and therefore my monitoring system promptly starts spamming me with alerts that my fan has failed - which is of course not true.

This is certainly caused by my old BIOS and its broken ACPI implementation, however since it's working perfectly fine otherwise I see no reason to replace it. That being said, I must be able to monitor my fan, so for now reverting the patch immediately "fixed" the problem for me - the fan entries appeared in sysfs again after successfully loading the module.
Idea, workarounds or patches welcome.
So Linus's tree is also "broken" for your hardware?
