Also are you accessing the nvme device e.g. /dev/nvme0n1 raw or via partition or filesystem?

Here are my experiments and observations so far: - The drive is usable for read operations and I can run fio (randread, etc) but I cannot write to it. - Other manufacturer's NVMe drive can be inserted into this platform and I can write to it - I can insert the intel P3700 into an x86 host and I can perform write operations - I have tried using the nvme-cli (https://github.com/linux-nvme/nvme-cli) tool and have read the error codes from read. It just shows 'WRITE_FAULT' which is not very helpful. - I have looked at the SmartLog reports and the 'Critical Warning' is 0, i.e. the device is not in Read-Only mode - I have updated the firmware using the intel SSD-DataCenterTool and updated the firmware on the drive the latest available version. The updated drive works fine on x86 platform. I think there is some combination of the platform and drive that is causing the problem. Can anyone offer pointers on how to debug this?
