Well, this is unfortunate. Even if I enable debugging in the kernel (BTW I
forgot to mention I use 4.19.288) nothing will be useful?

Well, I was considering to upgrade, but the investment is not worth it - I
calculated > €1000,- for controllers and NVMe disks. If I were to do
something like this, I would replace the whole machine as this one is
pretty old. The advantage with it is that it consumes around 80-90Watts in
total and newer once usually burn up more because of the CPUs.

What I would rather do is to plug in those SSDs directly to the mobo and use
the WD Red with 5800RPM in the bays.

Still, if you have any idea on how I can try debuggin it, please let me
know. I compiled the 4.19.288 with loggin enabled, but I am not sure this
is what I need.

I am attaching the full config below. If it is not asked too much, please
have a look and let me know if I missed something.
I will look forward to test it in Sept. when I have access to the server.

Thank you in advance
