Firstly, if this is not the right place for this message, I apologize.
In this case, disregard.

I have a problem which I suspect is a bug in libata, but of course I
could be wrong.

The problem is:
After going from Linux Mint 19.3 Cinnamon kernel 5.4.0-97 to Linux Mint
20.3 Cinnamon kernel 5.4.0-107 I discovered that I could not (reliably)
access my optical drive anymore.
It produces errors like:
ata1.00: exception Emask 0x10 SAct 0x0 SErr 0x40d0000 action 0xe frozen
ata1: SError: { PHYRdyChg CommWake 10B8B DevExch }
ata1.00: cmd a0/00:00:00:00:fc/00:00:00:00:00/a0 tag 0 pio 131072 in

0x80700 phys_seg 19 prio class 0
ata1.00: failed to set xfermode (err_mask=0x1)

The system was Linux Mint 20.3 Cinnamon with kernel 5.4.0-107-generic,
mobo ASRock model X570 Taichi.
After some tests I found out:
Kernel 5.4.0-99 works OK;
Kernel 5.4.0-100 has the problem;
Kernel 5.13.0-30 works OK;
Kernel 5.13.0-35 has the problem.

The problem is described more fully in

I reported the bug to the Launchpad Ubuntu site under number #1968155:
https://bugs.launchpad.net/bugs/1968155

One other person (as far as I know) has the same problem.

I froze my kernel at 5.13.0-30, so for the moment I can use my system.
I realize that there are probably not many users with an ASRock X570
mobo, and in that group only a few would be using a BD reader/burner.
However, it would be nice if I could again keep my kernel current.

With kind regards,
