I'm not sure about the "reboot=pci" but you might want to remove
"nomodeset" from your GRUB_CMDLINE_LINUX in /etc/default/grub,
then `sudo update-grub`.

Otherwise said, in details:

> GRUB_CMDLINE_LINUX_DEFAULT="quiet"
> GRUB_CMDLINE_LINUX="nomodeset reboot=pci"
Remove this:          ^~~~~~~~~~

  ^~~~~~~~~~~~~~~~~~~~~
And you might also want to uncomment that and introduce the
variable GRUB_GFXPAYLOAD_LINUX=keep to keep your Linux console
down to 80×25 characters, so the paragraph would become:

	# The resolution used on graphical terminal
	# note that you can use only modes which your graphic card supports via VBE
	# you can see them in real GRUB with the command `vbeinfo'
	GRUB_GFXMODE=640x480
	GRUB_GFXPAYLOAD_LINUX=keep

Not every graphical driver take this properly in account, but it
should be okay with raedon and amdgpu.

Once this is done, run the following command, and while it runs,
you should see your various kernels being listed.  This will
update the command lines at boot time:

	$ sudo update-grub

See how things evolve after issuing a reboot.
