Not for the exact symptom described in this report, but for an older S3 resume
issue that was partially resolved -
https://bugs.freedesktop.org/show_bug.cgi?id=103277 - I did once find the
regression caused by the "drm/amd/display: Match actual state during S3 resume"
commit.

Unluckily, the many changes that followed thereafter do no longer allow to
bisect the symptom there to one specific commit, but given that it still occurs
if I use the option "drm.edid_firmware=edid/LG_EG9609_edid.bin", I think there
is still some bug in the order of things done during re-initialization upon S3
resumes, and setting some fixed EDID seems to expose it as crash.
