I'm having issues with CMOS resets when running Big Sur with Opencore.
I tried the DisableRTCchecksum in Quirks, that didn't help. Then I tested with RTCMemoryFixup.kext and the method in boot arguments. That didn't help. I'm wondering what other issues would cause the CMOS reset as the troubleshooting guide at Dortania doesn't seem to point to anything but RTC issues. I do not get Safemode. Just reset notice each time on reboots or startups.
Solved with SSDT-Time-master tool which created RTC patches
