In addition to my other ask somewhere in this thread for increased debugging output to find your "real" problem, please give a try of this combo:
- 5.18-rc7
- Patch turning off reset on dGPUs in s2idle
- The below patch
This patch should do pretty much the same thing, try to recover your GPU when it's in this bad state. Now it happens somewhere more sustainable and sensible: on the resume path. I think this might get you a functional display rather than that "black screen" from the failed suspend cycle. It's still papering over your real issue of whatever caused the failed suspend.
I noticed the reset doesn't redo the HW init, that's still another needed step.
So here's a proper link to the patch you can apply as an mbox: https://patchwork.freedesktop.org/patch/486836/ This is untested.
