Hey,
thanks for the feedback and your work, didn't think this would be
interesting for anyone but the laptop owners.

it even suspends and resumes back to X
Wow, that's great news! Desktop Ryzen+Vega doesn't (not that I
need suspend very much on desktop haha)
Indeed, I was pleasantly surprised too
- xbacklight doesn't work, neither does intel-backlight because
it's AMD
Since it's a Thinkpad, do the brightness keys work anyway? Does
acpi_ibm work?
Forgot to mention brightness keys, they also don't work.
I just tried acpi_ibm and it also didn't help.
Serious issue:
I was just debugging this right now, more infos with a proper
bug
report will come, but I think the system encounters a deadlock
sometimes with the drm-kmod / amdgpu which results in a kernel
panic.
If you're on the packaged drm-kmod v4.16, it's amazing that
Raven GPU works at all. You should try drm-v5.0 from git.
kld_list="amdgpu"
Huh, interesting, I'm trying to compile drm-v5.0 right now.
This comment and Pete's made me re-visit the graphics settings,
specifics below.
It even works when loaded this early? Interesting. Do you also
not have the EFI framebuffer conflict? i.e. without disabling
vt.syscons, everything just works reliably?
Yes, with my previous laptop that was necessary, but this one has
no need for those settings, it works just fine without and font
size is according to the screen (i.e. it's not huge).

It is a serious issue, but it allows me to use the computer for
work,
it doesn't happen every couple hours, but it does happen a
couple
times a day.
FWIW, this is part of the crashlog:
WARNING !drm_modeset_is_locked(>mutex) failed at
/wrkdirs/usr/ports/graphics/drm-fbsd12.0-kmod/work/kms-drm-6365030/drivers/gpu/drm/drm_atomic_helper.c:821

interesting. can you post this kernel panic, and any backtraces
you are
able to get here:
https://github.com/FreeBSDDesktop/kms-drm/issues
also, are you using the xf86-video-amdgpu driver, or the stock
modesetting driver to X?
That was my plan for when I manage to fully isolate that it is on
drm-kmod, thank you for confirming the path!
I noticed I did have xf86-video-amdgpu installed, but just removed
it and all traces of drm-kmod as well as the kld_list="amdgpu" bit
and X actually works without it and without the xf86-video
packages.
HDMI output won't work though, I guess that makes sense.
We'll see if working like this the system doesn't crash at all, if
it does it may be related to #231760 and not to drm-kmod.
If it does not crash without drm-kmod, I'll try my build of
drm-kmod v5.0 before opening an issue, that'd be more information
:-).
I did have the question as to why the packaged version is 4.16 but
didn't quite find an answer to that on the wikis / documentation.
Thank you again,
