FWIW, while you were away I got an additional datapoint: someone who saw
my original post about this problem to one of the Linux From Scratch
mailing lists wrote me that he had the same problem, also getting
messages about the cdrom timing out ("sr 3:0:0:0" in his case); I told
him about your workaround of adding 'thermal.tzp=3D300' to the kernel
commandline, and he replied that this works for him too.  And it turns
out we have similar motherboards: I have a Gigabyte Z390 M Gaming
Rev. 1001 board and he has Gigabyte Z390 Designare rev 1.0.
