Nvidia RTX 5090 reset bug prompts $1,000 reward for a fix — cards become completely unresponsive and require a reboot after virtualization reset bug, also impacts RTX PRO 6000
CloudRift and community reports suggest a reset failure on Nvidia’s new Blackwell GPUs that bricks the card until the machine is power-cycled.
On guest shutdown or GPU reassignment, the host issues a PCIe function-level reset (FLR), which is a standard part of cleaning up a passthrough device. Tiny Corp, the AI start-up behind tinygrad, brought attention to the issue by reposting CloudRift’s findings on X.com with a blunt question: “Do 5090s and RTX PRO 6000s have a hardware defect? If FLR is unreliable, then multi-tenant AI workloads and home lab setups using virtualization become risky, particularly when a single card failure takes down the entire host.
