Can you a try a 4.19-rc2 or later kernel? Specifically, https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6d39df146ff12fb5c71634ad135144d5423590ec fixed this for me.
It doesn't appear to solve it. Instead I get a different problem earlier in the boot sequence, so it does not appear to reach the VCE code - dmesg extract below. The effect on me is that I don't get a visible prompt for my LUKS password, but if I type it in blind, _eventually_ the laptop display (and only the laptop display) shows an X-windows login. This behaviour occurs with *both* the kernel command line having amdgpu.dc=1 *AND* amdgpu.dc=0 - in other words the old radeon driver is also having problems here.

(In reply to Pontus Gråskæg from comment #2) > This behaviour occurs with *both* > the kernel command line having amdgpu.dc=1 *AND* amdgpu.dc=0 - in other > words the old radeon driver is also having problems here. Sounds like a misunderstanding here: amdgpu.dc=0 does NOT select the older radeon driver, instead it just disables the DC code base in amdgpu.
(In reply to Pontus Gråskæg from comment #2) > [ 2.619673] gfx7: Failed to load firmware "amdgpu/kaveri_pfp.bin" > [ 2.619798] [drm:gfx_v7_0_sw_init [amdgpu]] *ERROR* Failed to load gfx The new kernel reads the microcode from /lib/firmware/amdgpu/kaveri_*. Since you don't have those files yet, you can create symlinks to those in /lib/firmware/radeon/. Don't forget to update the initrd afterwards.
Sorry for the confusion. "The new kernel reads the microcode from /lib/firmware/amdgpu/kaveri_*. Since you don't have those files yet, you can create symlinks to those in /lib/firmware/radeon/. Don't forget to update the initrd afterwards." I will create the symlinks and retry, but might not be able to do so until Monday. Pontus
Created attachment 141473 [details] dmesg_4.19.0-041900rc2_dc.eq.1_initrdfixed
OK, symlinks done, initrd rebuilt Results are: With amdgpu.dc=0 System boots with normal behaviour. Laptop eDP screen works, VGA output works. I have no HDMI monitor to check if HDMI output works. With amdgpu.dc=1 I get a blank laptop screen (eDP) and (of course) no VGA, and I don't have an HDMI monitor to test the HDMI output. Given the problem I experienced before, I guessed that a blind input of my LUKS password would get me somewhere, so I enabled sshd beforehand so I could ssh into the laptop and save the dmesg ring buffer to a file. It shows a problem. I have extracted what I hope is the relevant part below, but have also attached full dmesg output for both the amdgpu.dc=0 and amdgpu=1 cases.

Just to be clear, booting with kernel 4.19rc2 does indeed remove the "*ERROR* VCE not responding, giving up!!!" and associated messages. So that can be marked solved (I think). However, there is still a regression in behaviour, but I'll raise a separate bug for that, as it appears to be a different issue. graaskaeg
Makes sense, thanks.
The new bug I have appears already to be documented: Bug 107595
