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 ED347CKR
monitor (https://www.acer.com/ac/en/US/content/model/UM.CE7AA.001) since Ryzen
doesn't VGA (https://bugs.freedesktop.org/show_bug.cgi?id=105880).

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

4.18 amdgpu.dc_log=1 amdgpu.dc=0 pcie_aspm=off doesn't boot, display
corruption. Colored line through boot text
4.19 amdgpu.dc_log=1 amdgpu.dc=0 pcie_aspm=off doesn't boot, display
corruption. Colored line through boot text
4.18 amdgpu.dc_log=1 amdgpu.dc=1 crash at boot and systems hangs, see
attachment 418_dmesg_boot_crash.log
4.19 amdgpu.dc_log=1 amdgpu.dc=1 crash at boot, system runs, see attachment
419_dmesg_boot_crash.log

All errors below are with 419 amdgpu.dc_log=1 amdgpu.dc=1.

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=off my console gets spammed infrequently with errors like:

[ 16.588103] pcieport 0000:00:01.2: AER: Corrected error received: id=0008
[ 16.588110] pcieport 0000:00:01.2: PCIe Bus Error: severity=Corrected,
type=Data Link Layer, id=000a(Receiver ID)
[ 16.588121] pcieport 0000:00:01.2: device [1022:15d3] error
status/mask=00000040/00006000
[ 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=off.

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.
