Thanks for contacting us!

That could be caused by two modules, either thinkpad_acpi or fan.

First, build a kernel with both modules not built at all and install
the kernel. The fan should work just fine as both fan and thinkpad_acpi
are not loaded. Then, build the battery and thinkpad_acpi modules and 
load one by one, and see which one causes the issue and report back.

Thanks,
Ognjen
