[SOLVED] System reboots after amdgpu driver is loaded

EDIT (SOLVED): I have resolved the problem by reseating the GPU.

Hi everyone, recently I have ran into an issue where after the AMDGPU driver is loaded, the system reboots after around 20 seconds, I am unable to even get into a TTY, but I do see bootup messages before the AMDGPU driver is loaded.

This issue started randomly, after the system has been perfectly fine for months. I tried multiple kernel versions 6.18, 6.17 and 6.12 and none of them work anymore, when they did before.

When I boot the system with the nomodeset kernel parameter, I am able to boot and get to a TTY, mode setting is failing, meaning I am unable to use the GPU.

This is dmesg from when the system boots but before it reboots after the AMDGPU driver is loaded: https://pastebin.com/jh8a6jQ7
(Sorry for the garbled output, this was copy pasted while SSHed into the pc through my phone)

The GPU is a Sapphire Pulse RX 6700 XT.
CPU: 6-core AMD Ryzen 5 5600 (-MT MCP-) speed/min/max: 3426/550/4468 MHz
Kernel: 6.12.31-gentoo-yaslam x86_64 Up: 7h 50m Mem: 4.05/31.27 GiB (13.0%)
Storage: 2.95 TiB (51.5% used) Procs: 394 Shell: fish inxi: 3.3.38
