My CPU is i3 10105, I think it should be 0x9BC8.
I used the patch for DS920+ on DSM7.1.1-42962, everything works just fine. jellyfin etc.
Last friday, I update to DSM 7.2-64570, I replace the i915.ko after updated as usual, then reboot.
well, it did reboot, and I can find it in the Synology Assistant for 1s.
then it shutdown itself. I can wol it again. then it will shutdown again.
I don't know what happened.
I assume it won't work on DSM 7.2 any longer.
so I can give a try on your test patches.
