Kernel log of the hang/crash

I've been testing kernel v4.16 on my computer, but it's basically unusable -
because after a few seconds or so after logging in it will do a soft lockup,
and I can't even switch to VT. I was, however, able to ssh in to it, which is
how I was able to get the kernel log. Right as the hang happened, I can see
this in the log:
Apr 11 14:04:13 homer-desktop kernel: [   45.532038]
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[CRTC:45:crtc-1] flip_done timed out
Apr 11 14:04:23 homer-desktop kernel: [   55.772028]
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[PLANE:37:plane-1] flip_done timed out
Apr 11 14:04:33 homer-desktop kernel: [   66.012282]
[drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR*
[PLANE:44:plane-7] flip_done timed out

and after that is the regular kernel crash.

I have tried this on both v4.16 and v4.16.1 with the same results. However, it
doesn't happen on v4.15 (which is what I'm running now). So there must be some
kind of regression between those releases.

I am running stable KDE neon (which is based on Ubuntu LTS) with precompiled
kernels from the ubuntu mainline ppa.
