I checked your Xorg.0.log and it looks familiar. Please look for post
"X11 hangs on StarLabs Mk IV - snapshot 06-06-2022" in the bugs@
archive and recent discussion in t...@openbsd.org:
"Xorg hanging on StarLabs Lite IV - infinite sleep in ioctl
drm_syncobj_array_wait_timeout"
Also, if you can boot a custom kernel, you could apply this patch to
confirm my findings:
https://github.com/ezaquarii/src/commit/0047e0f206896aa5287cad250c6bee1c994cdf88
https://github.com/ezaquarii/xenocara/commit/1d6e50bf668adfc07a4da0860d6c8f738ec1228a
Once applied, it dumps some traces via stdout (xenocara) and dmesg
(kernel). In my case, X hangs, but I can still SSH into the machine
to dump dmesg and do some things. When pkill -9 X, it locks the
machine for good.
I hope we are on some path to fix it.
@jsg FYI - it looks like we have another case of the Xorg hang on intel.
Best regards,

Thanks to Chris for a bit of hand-holding on getting diffs and files out
of github.
here's what got added to dmesg after I built and installed a kernel with
that patch on my "problem" machine:
