daemonix Posted October 31, 2019 Share Posted October 31, 2019 Everything regarding GPU passthrough was ok with my unraid servers (I have 3 servers all with Linux and Win passthrough VMs, for CUDA) but now one system will not boot any VM with passthrough. It works (randomly?) one the first boot after the install of a VM but then the GPU stops working (no CUDA calls work) at a random point. Error attached below.

I even upgraded to the latest RC unraid but no luck. Any troubleshooting advice? Quote Link to comment
