under  Tumbleweed  when  upgrading  to  kernel 5.18.1  or 5.18.2  I have  2
NVME  SSD from the  same   manufacturer 
lspci - nn  output
Non-Volatile memory controller [0108]: Phison Electronics Corporation E12 NVMe
Controller [1987:5012] (rev 01)

I get a fault after boot  and only  one  nvme SSD  is  recognized.
error  message  is   duplicate IDs  for  nsid.

under kernel 5.17.4-1-default  I don't get this error.

My understanding  is  that  in previous  kernels  there was a quirk enabled 
for SSD  manufacturers  that  exhibited this  issue. 

under kernels 5.18.1, 5.18.2 and  5.17.4   if  i execute  dmesg and  grep  for 
nvme  I see  the  message  

missing or invalid SUBNQN field.

can you review  and reenable  NVME_QUIRK_IGNORE_DEV_SUBNQN  if this is this is
issue?

Also  note in my case multipath  should be disbaled, as  the  ssd are  used 
independently
