[Nouveau] acr: failed to load firmware with Kernel 5.6. Kernel 5.5 works just fine.
Ben -- probably the ACR changes in 5.6 don't fall back nicely anymore when there's no firmware? The load shouldn't be failed, just GR disabled... Zeno -- if you grab linux-firmware, it should be all better. Not sure if you're missing it on purpose or by accident.

So far linux-firmware was not needed with Kernel 5.5, so it was not installed on my machine. [ please CC me ] Best Zeno

It's just that it fell back gracefully without firmware, and you didn't get any acceleration features. Cheers, -ilia
