I guess you mean building *without* CONFIG_CDROM=y, since CONFIG_CDROM=n doesn't seem to be a valid Kconfig setting. In order to remove CONFIG_CDROM=y I had to unset CONFIG_BLK_DEV_SR (I couldn't see how to do this with `make menuconfig' with the existing .config loaded, but I could do it with `make xconfig'). Anyway, I did that with the problematic kernel 5.3.0, rebuilt and reinstalled the kernel, booted it, confirmed that there was no /dev/cdrom, ran startx, emacs, firefox, exited these, ran `shutdown -h now', and as previously with this kernel, after the loopback interface message there was nothing more, and after waiting more than two minutes I pressed the restart button. So it looks like detaching the cdrom is not the problem after all.

Although the cdrom is evidently not the problem, I guess I've reached the point where bisecting is the next thing to try.
