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,

It's in milliseconds. The default when not set uses the kernel's
default, which is 60 seconds, or 60000 milliseconds.
