Public bug reported:
dmesg shows issues with being able to use the discrete graphics card
(relevant dmesg lines attached).
Grub does pass "radeon.modeset=1" and "radeon.startpm=1" to the kernel.
I've tried all combinations and same results occur.
Attached are relevant dmesg lines, grep'd with 'drm'. I'll also be
attaching entire contents of dmesg, /var/log/syslog, etc., but TLDR:
