Guru Needed: AsRock X670 PG Lightning interesting strange shutdown reboot only after 1.3 BIOS

[Jumper981]

Hi!
After updating to latest BIOS on my AsRock X670E PG Lightning a bunch of problems arises. Ethernet not working (was resolved modifying the kext RTL812xLucy deeply, a post will be made).
Unfortunately i'm stuck and not properly working Shutdown and also sleep and wake. i've tried making some patches to DSDT on my own but without success i'm wondering if my bios need the patches in this post.
Both bioses attached 1.21 that was working and 3.5 that was not working. all the bioses after and included 2.0 exibit those problems.
Can someone help me?
Thanks

Your shutdown troubleshooting doc is a fascinating read, so thanks for that.

Not sure why you expect anyone else to offer anything more with regards your testing and ruling out specific issues seen in the various logs. I for one don’t go that deep into troubleshooting issues, not when there is a straightforward solution to hand.

I struggle with why you moved to the new bios, when everything worked in the older bios, including the shutdown/wake issue. Was there something specific in the new bios that your system couldn’t do without?
