[Partial Success] Ventura on X99

[rubenhak]

Hi, I have a partial success with running Ventura. The only issues is that initial boot is not always successful. Sometimes it boots at once. Sometimes it may take 5-20 reboots for OS to boot. It is intermittent. Once in the OS, things work great. LAN, Wifi and iMessage works. Would appreciate some help here. Thank you!

@rubenhak  Took a quick look at your dsdt.aml. Made a few changes, related to HPET/EC/RTC. Not sure if this solves your problem. But worth a try. Also, you don't need the patch (RTC_STA) in your Config.plist->Root->ACPI->Patch, so disable it (already in the new dsdt patch). Give it a try.  Goodluck!

@rubenhak When it failed to boot, what kind of error was it? I am wondering if you just need to perform a TSC Reset before launching Monterey.  See this link here.
