This is similar but not quite the same bug as #107829

I recently updated arch linux and attempted to use the nouvea driver with my
GTX 660 GPU. System will reliable crash after about 30 seconds to 1 min in KDE
plasma with the following kernel message.

Placing nouveau.noaccel=1 as a kernel boot parameter fixes the issue but it is
not ideal.
