Versions 460.56 and 460.67 of x11-drivers/nvidia-drivers fail to start at boot with the following error in syslog: NVRM: API mismatch: the client has the version 460.56, but NVRM: this kernel module has the version 460.39. Please NVRM: make sure that this kernel module and all NVIDIA driver NVRM: components have the same version. Downgrading to 460.39-r1 solved the problem. True of both 5.4.109 and 5.10.24 kernels. See forum post for more information: https://forums.gentoo.org/viewtopic-p-8595198.html Reproducible: Always
Think the message is already clear that you're loading the wrong module, NVIDIA drivers needing to match libraries been a requirement since the early 2000s (nothing new, ask upstream if you want new libraries to work with old drivers). I don't see any reason to include nvidia-drivers on an initramfs as it's not needed for bringing up filesystems. This also doesn't seem to be an issue with gentoo-kernel{-bin,}[initramfs] The newer ebuilds (since 460.67) already have a warning in the ebuild about mismatch and I expect users with custom setups to know how to handle it: ewarn "Currently loaded NVIDIA modules do not match the newly installed" ewarn "libraries and will lead to GPU-using application issues." This warning is also included in 390.141-r1 and 450.104.04-r1 LTS branches and will be stabled sometime later this month (460.39/56 are due for removal after a grace period).
