Re: x11/nvidia-driver update to 470.63.01 seems to break GK106GLM [Quadro K2100M]

See if it is reproducible with a 13 or main kernel, there is a locking change

be a good thing to know.  This may need nvidia help since the error
seems to be deeper in the blob, they have a support forum where you
can link your report to start that.
