Details

After upgrading to linux-5.18.1.arch1-1 a second identical nvme device is no longer found/visible. Only one of the 2 devices is visible in the /dev tree. This breaks/degrades raid-1 configurations.

Downgrading to 5.17.* fixes the issue atm.

The 5.18* kernel throws the error:
"globally duplicate IDs for nsid 1"


The device list under 5.17:
nvme list

This task depends upon

I think you may need to add a quirk disabling namespace identifiers for those devices [1] similar to [2] the duplicate checking logic was broken before 5.18 [3]
Edit:
Assuming the devices 1987:5016 which already have an entry which you could adjust as in the attached diff
Edit2:
[4] confirms a quirk needs to be added for devices which break the standard, by reporting the issue upstream.

Updating the kernel version from 5.18.5 to 5.18.6 did not solve the problem. So, adding the quirk [1] worked for me.

Candidate for a cherrypick?

Upstream fix/quirk is included in core/linux-5.18.14.arch1-1

Ahh, thanks. I was looking for the quirk mentioned by @redshoe. That one will end up in a future kernel anyway so I will close this ticket.
