Maybe /etc/pacman.d/mirrorlist provides a mirror that isn't provided by /etc/pacman.d/mirrorlist.pacnew anymore and this or something else does cause partial upgrades, since 4.19.8.arch1-1 is the latest official kernel, see https://www.archlinux.org/packages/core/x86_64/linux/. If so or if not, before continueing troubleshooting I would install the latest kernel. Was anything else updated before the issue appeared? Was the last update done at 4 December or is it just the date of the kernel update? There is nothing related inside any log file?
