Well the "[drm:intel_dsi_vbt_gpio_init [i915]] *ERROR* Failed to own gpio for panel control" error is gone.

I just noticed you describe the problem as "blank screen with a cursor" , I should have noticed this before. I assume with a cursor you mean a mouse cursor (and not a Linux text console cursor. So you are likely hitting the issue I mentioned before where we hit a GPU freeze and indeed looking closer at the logs that is exactly what is going on:

Apr 09 08:34:55 SrLungACI kernel: i915 0000:00:02.0: GPU HANG: ecode 8:1:85dffffb, in Xorg [938]
Apr 09 08:34:55 SrLungACI kernel: GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

I have checked and there already is an upstream bug report for this:

https://gitlab.freedesktop.org/drm/intel/-/issues/1605

To which I have added some details about the times when I hit this + a link to this bug.

What might be helpful is if you can configure ssh on your machine, then ssh in while it hangs (that should still work) and do:

sudo cp /sys/class/drm/card0/error i915-crash-dump

And then attach both the dmesg output from that boot as well as the i915-crash-dump file to the upstream bug report:
