Is it a regression? Did it work in older release like 16.04?

No. 16.04.6 have this issue too.

Can you please test the GA (4.4) kernel on 16.04?

I checked the bug on kernel 4.4.0-21-generic ubuntu 16.04. Bug is present.

Ubuntu 21.10 bug is present.

I have the same log, even while not using the CD/DVD drive (and not having a disc inside)

Can the optical drive read CD/DVD/BD correctly?

Yes.

So what we need to do is to lower the log level?

I think this is a symptom of a bug which cause we don't know and need to
find out.

The fact is that: 1) the system touches the device (sr0) when the user does not touch the device (at boot and constantly while the system is running),
2) these calls from the first paragraph cause errors.
We want to 1) fix these errors, 2) remove unnecessary calls to the sd0 device.
