Hi Guo, thanks for your tests! So, to confirm:
a) With Ubuntu kernel 4.15.0-34, using the kernel parameter "nvme_core.multipath=0", you _don't_ see the issue; b) With kernel 4.17.0-041700rc1-generic, even using the parameter "nvme_core.multipath=0", you *can reproduce* the issue. Right? I've noticed that the fix patch is present in v4.17-rc4, but I see a "rc1" in your kernel version - it could explain why even in this 4.17 version you can reproduce the issue. I'll build an upstream 4.17 and re-test in my environment, to double-check if it fixes for me.
