Nouveau - Apr 2020 - Error -28

I?m having trouble getting my GTX 1050 Ti working in Debian Sid. This machine is
a PowerMac G5, 2.3 GHz Dual Core. I?m using a Quadro FX 4500 as well and it
seems to work as expected. I?ve installed the firmware-linux-nonfree package,
which seems to have the required firmware for the GTX 1050 Ti. In dmesg I see
this error after some lines which mention ?direct-loading firmware?:

    nouveau 0001:06:00.0: gr ctor failed, -28

Any ideas on how to fix this?

Does it print anything else before that?

There's definitely some dubious endian-unsafe code in the later
nouveau stuff. For example, nvkm_falcon_v1_read_dmem seems to make
assumptions about CPU being LE, based on a quick read of the code, and
I would expect the file header parsing stuff does too.

Cheers,
