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.
