nvme0: missing or invalid SUBNQN field.

[onepamopa]

Hey guys,

I switched to a new nvme SSD today (the last one - ADATA XPG had some troubles).
The new SSD is Samsung SSD 970 EVO Plus 1TB

All good so far, but I noticed the following in the log:

# dmesg |grep "nvm"
[ 0.757426] nvme nvme0: pci function 0000:47:00.0
[ 0.977430] nvme nvme0: missing or invalid SUBNQN field.
[ 0.977444] nvme nvme0: Shutdown timeout set to 8 seconds
[ 1.007025] nvme nvme0: 32/0/0 default/read/poll queues

Should I be concerned ?

Here's output of smartctl:

hi,


i think this is a firmware related warning but shouldn't have any impact on the performance of the disk.
also smart says no errors are logged, so it's probably okay.
are there any other logs of interest?

i wouldn't worry if there's nothing else and the disk works fine
