Nevermind - I don't think I'll need the logs, I stared at the code for long
enough and I think I realized what's happening.
I will have a patch for you to test in just a moment, just waiting for it to
compile so I can verify nothing else breaks

Hopefully you're still on at this point - if you are, could you try starting
the machine up with the following kernel module arguments passed to nouveau?
debug=disp=trace
Then see if you can find any lines that mention INHERIT? I have a feeling I'm
just going to have to add a workaround for the
agh - thank you for repeatedly poking on this, I've been busy enough with GSP
work I totally missed this. Yes - I'm quite surprised that this is blowing up,
but considering that looks to be a GT218 I guess display state readback must
just work a bit differently there since that's really early on

Not only that - panic_on_warn turns this into an explosion so you don't
want that in a released kernel.
