I did some testing on kepler and it looks like it is broken. I can reproduce the Talos + transfer queue issue there easily. I wrote https://gitlab.freedesktop.org/mhenning/linux/-/commit/b3ef72898ae2bf19cf587b8679d193c9570ddb05 to fix the membar half of the issue but that still doesn't load Talos with a transfer queue, which means that we either need to apply this fix (nouveau: fix disabling the nonstall irq due to storm code) for kepler and probably all the other gens, or there's yet another bug lurking somewhere.
