Huh, that’s certainly interesting! The hacky solution ended up having to do with power states which is kinda annoying - I have to set the GPU to use max power state because if it goes into the min state and then I walk away for 5-10 mins, it drops out of the PCIe slot and I need to reboot. SSH still works but you can’t reattach it w/o a reboot. I’m running a PCIe gen 5 mobo though and I heard about some potential problems with that, so maybe that was related. Could also be the fact that I ran a Quadro RTX 4000 on the same system/OS for a year or so and didn’t want to do a full reinstall, so it probably had somewhat to do with leftover drivers and crap
