@dinhngtu I can't say on XCP-ng side, but it's likely linked to: August patch (and following), as Microsoft changed something to the NVMe stack. e.g. https://learn.microsoft.com/en-us/answers/questions/5536733/potential-ssd-detection-bug-in-windows-11-24h2-fol Google gives a lot about it. It seems that it most likely doesn't kill NVMes but can cause trouble. We have a few PCs becoming more unstable (BSODs) or even very slow after that upgrae.
