I rebooted into the freshly installed 5.3 system and it worked
perfectly.  The upgrade went fine also.  It was only upon booting into
the 5.4 kernel that I had problems.

It is.  That should read "CDROM drive (master on ata1)".

That's correct.

I believe so.  I'm not near that machine presently, but I know it found
the ATA PCI controller because it was able to find the CDROM drive.  I
know it displayed a message saying "ata0: something or other".  If it
displayed anything (not an error) does that mean that ata0 was found
then?
