So after upgrading from an old generic ssd to a wd black sn750, I am seeing this message constantly on my log, nothing seems to be wrong with the server but makes any kind of debugging impossible since it happens every 5-10 seconds. Why is this happening and how do I fix it?

Have a look at this post from Jorge.

Sadly this did not fix it, I don't have another m.2 slot on my motherboard so can't move it around and adding 

pci=nommconfto did not do anything

 

Edit: not sure how much this matters but I am booting in legacy mode on my motherboard, UEFI boot makes unraid not able to see my nvme for some reason

Did you manage to resolve this?

 

I'm getting the same thing for my NVME drive as well and it fills the log file in a matter of hours.

 

 kernel: pcieport 0000:00:01.1: AER: Corrected error received: 0000:02:00.0
 kernel: nvme 0000:02:00.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID)
 kernel: nvme 0000:02:00.0:   device [144d:a804] error status/mask=00000001/00006000
 kernel: nvme 0000:02:00.0:    [ 0] RxErr  

I've managed to find a solution by using a different command in the syslinux configuration.

 

append initrd=/bzroot pci=noaer

 

Apparently pci=noaer disables Advanced Error Reporting. Unfortunately its a bit like pulling the bulb behind your check engine light on your car but not sure how else to disable these warnings. There are some other options as well which i might try and see if they also work.

 

pci=noaer

or

pci=nomsi

or

pci=nommcon

 

Found this info here: 

 

 

 

See more details here: 

 

 

And Here: https://askubuntu.com/questions/1104219/what-does-pci-noaer-or-pci-nomsi-mean

 

 

 

 You need to add this to your syslinux. It prevents the nvme drive to go in the deepest sleep mode. Remove pci=noaer, because it only hides the problem.
