Random reboots while loading the system

[macpro]

this is the place where the computer restarts, any tips?

what is the make and model of your nvme?

- ACPI files are not loading in sorted order - done
- Renames are depreciated and handled by Lilu, WEG and AppleALC itself - done
- FadtEnableReset and ResetLogoStatus shouldn't be needed for your hardware - done
- EnableWriteUnprotector shouldn't be needed for your hardware - done
- ResizeAppleGpuBars must be set to -1 - 0 is required when resize GPU bar activated in BIOS
- Remove all the Device properties - I need some of them
- Kexts are not loading in sorted order. Important kexts should load first - done
- CustomSMBIOSGuid shouldn't be needed for your hardware - I need this
- NootRX shouldn't be used as 6900XT works OOTB - done, new SSDT added
- SetApfsTrimTimeout must be set to default - done
- HibernateSkipsPicker and PollAppleHotkeys shouldn't be needed as well - done
- Do you really need the Ntfs and Ext drivers? - done

But the system's behavior hasn't changed. The problem persists. The system does not start every time properly. From the log files, it seems to me that these are some NVRAM issues.

Any other tips?

Remove BrcmBluetoothInjector.kext and NVMeFix.kext and then check. DisableRtcCheclsum shouldn't be needed as well.

Attach a copy of IOReg as well.

I found the cause of these symptoms. It wasn't due to incorrect settings. Besides the Sequoia, I have a Tahoe on a second drive. Apparently, the presence of a second Tahoe drive causes these errors and random restarts. The problem manifests itself during OpenCore loading and slide allocation. Interestingly, when I had Sonoma on one drive and Sequoia on the other, there were no such problems. Another interesting thing is that when I already have Sequoia installed on one drive, the Tahoe installer can't handle the Tahoe installation. If the situation is reversed, i.e., when I already have Tahoe installed on one drive, I can easily install Sequoia on the other. Has anyone had similar observations? The problem requires further investigation.

Having Dual Drives where macOS is installed, shouldn't create any problems as long as the EFI is up to the mark and hardware has no potential problems.

Do you currently have both Tahoe and Sequoia installed on two different NVME drives? This problem only occurred with this configuration. When I had Sonoma and Sequoia, this wasn't a problem. Another thing is that back then, I had one system installed on a SATA drive and the other on an NVME drive. Perhaps that also has something to do with it.

How about you disconnect one of these drive and then check? Can you mention the drive models in the question?

I'm using WD Black SN850X drives. As I mentioned earlier, when I disconnect one drive and leave the system on one (no matter which one), there are no problems and no freezes or restarts. Again, I didn't have these issues when I had a Sonoma on one drive and a Sequoia on the other. But this may not be a representative example, as I had one system on an NVME drive and the other on an SSD, and that can also make a difference.

Are both the boot drives (Tahoe and Sonoma) SN850X? If not, then please mention the particular model in question.

Also, does it matter which specific drive you disconnect or is it any of the drive (either Tahoe or Sonoma)?

1) all drives are SN850X
2) doesn't matter
