Perhaps serious NVME-driver issue ^PRP OFFSET INVALID^


Using an NVME SSD in my TrueNas system based on FreeBSD 12.3 as well as the
version based on FreeBSD 13. Every 5 minutes I there are two messages

nvme2: GET LOG PAGE (02) sqid:0 cid:10 nsid:ffffffff cdw10:00ff0001
cdw11:00000000
nvme2: PRP OFFSET INVALID (00/13) sqid:0 cid:10 cdw0:0

The system I am using is based on an AMD X64 processor the SSD is a 2TB XPG
Gammix S70 Blade PCIe Gen4. However from the internet I know the problem also
occurs with other SSD's.

Searching the internet for this problem, I found a couple of sides describing
the issue also sites where oracle and marvell engineers where discussing
patches.

I do not know if those / equivalent patches are also applied to the actual
FreeBSD NVME-driver, however given the fact that the messages are still there,
I have doubts.

I also do not know to which extend the problem can lead to data corruption,
however I do not feel comfortable!

Below a couple of links related to the subject. 

Please let the driver developer have a look at the problem and the links given
below.
