<span class="quote">> Can you try booting with amdgpu.dc=0 in your kernel boot parameters?</span >
As noted in the original bug report, "passing "amdgpu.dc=0" on the kernel
command line resolves the problem." The "successful boot" logs I've provided
were all captured under that setting, since the system is unusable without it.
I *suspect* the system is booting fine apart from the graphics, because when
Fedora reboots to apply updates, it does so successfully before powering off as
expected – I just can't see anything on the screen.</pre>
