So I tried the GSWApp ACPI patch in that link ("Replace ADBG with XDBG") and unfortunately it made no difference. My Mac still hangs / panics just before entering S3 state on the
second sleep. The power light stays on and pressing the power button/keyboard just restarts the PC.
I've tried various other things including:
- Disabling Thunderbolt (in UEFI)
- Adding SSDTs / Patches from

- Disabling Intel Bluetooth kexts
Nothing seems to work and I'm a little stuck. There are ACPI warnings in my boot log (attached), but I'm not sure if they are a problem or not.
Since the Mac works fine after the first sleep cycle, I guess something is not being initialised correctly when waking from that first sleep - which leads to the hang on the second sleep. But I'm not sure how to diagnose this further.
