We are experiencing some issues with Skydel running on Ubuntu 22.04.3 LTS with the hwe kernel 6.5.0-17-generic paired with an Nvidia RTX 4070. We have tried a couple different Nvidia driver versions all installed using the method described in the Skydel User Manual but we seem to be having different issues with each one. Currently we are using driver version 535.154.05 but after running a couple simulations we are experiencing the following error in our
simulator.log (8.5 KB)
that causes our simulation arming to fail:
2024-02-12 08:06:01.339850: Unable to create UHD Streamer: RuntimeError: On node 0/DmaFIFO_0, input port 0 is already connected.
This error has also resulted in our GPU showing Skydel taking up a lot more VRAM than normal, despite Skydel being in the Ready state:
Looking at our kernel’s ring buffer per dmesg we are also seeing the following Nvidia error:
Has anyone experienced these issues with a newer 40 series Nvidia GPU? We would appreciate any insight on what may be done to fix the instability. If there are Nvidia drivers that have been vetted by the Skydel team then we would like to use them.
