Recently, when running an nvme-format against some HGST NVMe drives, I saw some odd errors crop up in syslog that all looked like this. I've seen it on a few systems now and have become a little more concerned.? I've seen references to this around the mailing list, but am a bit confused. Is this a kernel bug, or is it likely to be a hardware issue?
Oct 14 09:45:45 localhost kernel: nvme 0000:05:00.0: I/O 1 QID 0 timeout, reset controller
For reference, I'm running Centos 7.2 with the 4.4.1 elrepo kernel and nvme-cli 0.8.? I'm running these two commands in sequence:
nvme format -s 1 /dev/nvme0n1
nvme format? /dev/nvme0n1
Thank you,

Hi Zeta,
a format will probably require a longer timeout than the default 60
seconds, try specfing ? --timeout argument with a longer timeout on the
nvme-cli command line.

I tried -t 3600 for an hour, but it hung the couple of systems I tried it on. What exactly does that timeout do? And is it not in seconds?
Thank you,
