--- Comment #5 from Paulo Zanoni <przanoni at gmail.com> ---
We get those interrupts because we're reading registers that are on the
disabled power well when we are at the function that collects data for the
error state file.

I sent a patch fixing this a long ago, but Daniel Denied it.

If we fix the GPU hang, the problem will go away.
