Hi, is this actually an nv50 GPU, or some other model? I can try to take a closer look at this

The fastest way to identify the problem would be to do a bisect on the kernel to identify the commit that caused this. There are many guides for this online.
Unfortunately, even with this change now reverted in kernel 5.1.10, the fan speed issue persists.
If someone could point me in the direction of a relevant commit(s) I'll happily file a bug report.
As of kernel 5.1.9, on resume from suspend, my NV50 fan runs at full speed.
Not sure if it has to do with this new config option (NOUVEAU_LEGACY_CTX_SUPPORT)?
This issue is not present using kernel 5.0.21.
Years ago I filed a similar issue:
Thanks.
