After blacklisting the amdgpu module via echo "blacklist amdgpu" >
/etc/modprobe.d/blacklist-amdgpu.conf && update-initramfs -u; the system
will let me boot all the way up with more than one RX580 installed
(currently two are installed). Running modprobe amdgpu after the system
was already booted cause a kernel panic, which I have captured and
attached a screenshot of below.
