/sys/class/drm/card0/error crash dump

Taking laptop out of suspend, the UI frequently hangs a few seconds after resume for around 18 seconds. Occasionally it will hang indefinitely and must be rebooted, but I'm unsure if that behavior is related to the momentary hang.

While in this hung state, I can't switch to another VT. I haven't tried Magic SysRq in this state yet.

How to reproduce:
  Put laptop into suspend
  Resume from suspend and begin typing/mousing
  After ~3-5 seconds, UI will hang

These steps reliably reproduce the issue, as far as I can tell this happens every time.

System info:
  $ uname -rvspio
