I have continued to research this issue. In the meantime, I have also upgraded to Ubuntu 17.10 and the issue persists with kernel 4.10.0-19.
My research eventually turned up this thread containing a workaround for the problem: https://bbs.archlinux.org/viewtopic.php?id=221391
Kernel 4.10.0-19 will boot correctly with the radeon driver loaded and functioning by adding the following kernel parameter to grub: radeon.dpm=0
