atm I've got access to just one other Ryzen box, with a non-GPU cpu, and a slightly
newer Nvidia pci card,
cat /proc/cpuinfo | grep "model name" | uniq
model name : AMD Ryzen 7 3700X 8-Core Processor
inxi -G | grep Dev
Graphics: Device-1: NVIDIA GP108 [GeForce GT 1030] driver: nvidia v: 470.74
but otherwise similarly setup (F34, kernel, etc); no problems with exactly the same nvidia
build procedure,
lsmod | grep -i nvidia
nvidia_drm 69632 7
nvidia_modeset 1200128 23 nvidia_drm
nvidia 35332096 1557 nvidia_modeset
drm_kms_helper 303104 1 nvidia_drm
drm 630784 13 drm_kms_helper,nvidia,drm_ttm_helper,nvidia_drm,ttm
headers & version magic all seem to match on both systems
other than the nvidia mod insertion fail, there are no other, obvious problems; not clear
to me what/why is possibly machine/env-specific ...
i've been chasing a solution, so far with no luck :-/
any suggestions as to what the cause might be, and any fix?
