How to Fix, GPUs went to Unsupported after reboot
Posted: Thu Aug 28, 2025 7:56 am
I have a test platform with 8 Nvidia H800 GPUs. Everything worked fine for two days (ArchLinux, fah-client 8.4.9, Driver Version: 580.76.05, CUDA Version: 13.0), but in the morning after rebooting, all GPUs are shown as unsupported. My GPU is present in a GPUS.txt file (0x10de:0x2322:2:9:GH100 [H800 PCIe]). What went wrong?
