Unable to boot without nomodeset option, ATI Driver Issue

I have recently installed Arch Linux on my laptop. Everything seems to be working alright with the exception of one issue: I am unable to boot without using nomodeset. If I attempt to boot without it, it will start the boot process, but after a few seconds, the screen will quickly fade into white, before turning off completely. The fans in the laptop will turn off, and nothing will happen until I reboot the system.

When I hook up the laptop to my television, I am able to see what is happening somewhat. It seems to load normally with the exception of this error message popping up:

[drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery failed

Then the television screen goes blank, and nothing happens after that. I presume it has something to do with how X loads.

I am able to boot into the system when loading the generic vesa driver, but of course, it makes everything look pretty ugly, and is unable to detect the proper resolution of my laptop's screen.

The laptop is an ASUS K53Z, the CPU is an AMD A4-3305M, and the integrated GPU is a AMD Radeon HD 6480G. Current driver installed is xf86-video-ati 1:7.10.0-1. Current kernel is 4.14.6-1.

I've scourged the internet for possible solutions to the problem, but none have worked. I've tried various other options at boot such as acpi_osi=linux, acpi_backlight=vendor, radeon.dpm=0, etc. I've tried using the LTS kernel. I've added radeon as a module to my mkinitcpio.conf. I've checked to see if radeon is being blacklisted anywhere.
