4.19 dmesg crash at boot

I recently switched from a dual monitor setup with 1 HDMI and 1 VGA monitor
(connected through a powered HDMI -> VGA concerter) to a QHD 34" Acer ED347=
CKR
monitor (https://www.acer.com/ac/en/US/content/model/UM.CE7AA.001) since Ry=
zen
doesn't VGA (https://bugs.freedesktop.org/show_bug.cgi?id=3D105880).

It solved that crash, but it introduced a new crash.

4.18 amdgpu.dc_log=3D1 amdgpu.dc=3D0 pcie_aspm=3Doff doesn't boot, display
corruption. Colored line through boot text
4.19 amdgpu.dc_log=3D1 amdgpu.dc=3D0 pcie_aspm=3Doff doesn't boot, display
corruption. Colored line through boot text
4.18 amdgpu.dc_log=3D1 amdgpu.dc=3D1 crash at boot and systems hangs, see
attachment 418_dmesg_boot_crash.log
4.19 amdgpu.dc_log=3D1 amdgpu.dc=3D1 crash at boot, system runs, see attach=
ment
419_dmesg_boot_crash.log

All errors below are with 419 amdgpu.dc_log=3D1 amdgpu.dc=3D1.

I see a difference in crashes when I boot with my monitor on or off.

Monitor on at boot (419_dmesg_boot_crash.log):

Without pcie_aspm=3Doff my console gets spammed infrequently with errors li=
ke:

[ 16.588128] pcieport 0000:00:01.2: [ 6] Bad TLP

The first time I saw those was with 4.16, but they don't occur every boot. =
I'm
not sure if those were present <4.16. I'm aslo not sure if this is still
present at 4.19. I'll soon find out since my system no longer boots with
pci_aspm=3Doff.

When running 4.19 I sometimes see

(EE) AMDGPU(0): drmmode_do_crtc_dpms cannot get last vblank counter

in xorg.log. See 419_Xorg.0.monitor_off_at_boot.log

I tried 4.20rc2 (I can't get newer RC's to build the Manjaro way) but it has
identical errors as 4.19.

Also attached lspci -nnk | grep VGA -A 12.

All errors below are with 419 amdgpu.dc_log=3D1 amdgpu.dc=3D1.

I see a difference in crashes when I boot with my monitor on or off.

Monitor on at boot (419_dmesg_boot_crash.log):

Without pcie_aspm=3Doff my console gets spammed infrequently with errors li=
ke:

[ 16.588128] pcieport 0000:00:01.2: [ 6] Bad TLP

The first time I saw those was with 4.16, but they don't occur every boot. =
I'm
not sure if those were present &lt;4.16. I'm aslo not sure if this is still
present at 4.19. I'll soon find out since my system no longer boots with
pci_aspm=3Doff.

When running 4.19 I sometimes see

(EE) AMDGPU(0): drmmode_do_crtc_dpms cannot get last vblank counter

in xorg.log. See 419_Xorg.0.monitor_off_at_boot.log

I tried 4.20rc2 (I can't get newer RC's to build the Manjaro way) but it has
identical errors as 4.19.

Also attached lspci -nnk | grep VGA -A 12.
