I suspect that the Debian kernel can load the compressed firmware and just emits a misleading error message about the non-existing uncompressed files before it finds the compressed ones. (That would be easily verifiable by moving the Debian files out of /lib/firmware/nvidia without placing the compressed Fedora files there. If it behaves differently than with the compressed files, they are used.) > I had to use the rescue kernel to login and revert the changes. > > Another thing I noticed is the GPU fan, On Debian I can always hear it, its > not high, but audible, With Fedora, when the firmware files load on boot, I > can hear that fan slow down to an unnoticeable level.

Either that or Fedora has driver or config changes on top of the nouveau driver that are missing in Debian. Yesterday I tried to find the Fedora kernel sources archive, but I only found something older. Do you happen to know where to look for these? If it was only firmware files then it had to be good with Debian kernel + the Fedora firmware versions. If you want to you can test with the Fedora tree and run: find /lib/firmware -name \*.xz -print0 | unxz --files0 (untested, the intention is to uncompress all files). My expectation would be that this behaves in the same way as with the compressed Fedora firmware files, just without the error messages. > Is this something that could get pushed into Trixie yet?

So even if an update helps you, it might break someone else's setup ... But sure, a local modification is possible once we found the culprit. Best regards Uwe
