--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Interesting. The only write I see to that register is in the GM107 fan control
logic. This is not used for GM200+, as controlling the fan can't be done
anymore, except via secure firmware means.

So ... my *guess* is that this is a write failure that happens as a result of
the firmware that gets loaded, which is not supplied by nouveau. (Always
preferable to blame someone else...)

Can you get a dmesg with nouveau.debug=trace which should place that error more
exactly in the initialization flow.
