macOS Mojave 10.14.6 restarts randomly after boot

[tsmswifty]

There isn't even a kernel panic that occurs, it just blacks out and restarts randomly a bit after boot. Sometimes this doesn't occur, but most of the time it does. Anyone else having this problem?

It seems to be a "shutdown stall", logs here:

you should be disabling your nvidia graphics as that isn't compatible with Mojave:

    <dict>
        <key>InjectKexts</key>
        <string>Detect</string>
        <key>InjectSystemID</key>
        <true/>
        <key>NvidiaWeb</key>
        <true/>

this should also be disabled:
disable port limit in XHCI kext (credit RehabMan, based prior PMHeart patch)

SMCHelper.efi should be removed and virutalSMC.efi should be in it's place

Fixed those, though the sudden reboots are still occurring. Is there any better way of troubleshooting this? It either reboots just when I get onto the desktop or it never happens again till I reboot.

I see you are using ApplePS2SmartTouchpad.kext, unless it is for a good reason, I think you should change it to VoodooPS2controller version 1.9.2. Check out https://github.com/RehabMan/OS-X-Voodoo-PS2-Controller/wiki/How-to-Install

My keyboard and touchpad don't work with Voodoo

Unless I'm missing a patch or something

So I figured out that it was a kernel panic, but when I boot with debug=0x100 instead of rebooting on kernel panic it freezes, without anything about the KP displayed. How can I fix this?

@tsmswifty: have you found out the root cause? I am having exact same behavior.
My Hackintosh (Gigabyte Z390 M GAMING, rev. 1.0, AMD Radeon RX 580) was running smooth for the last 18 month - no problem ever after the first installation of Mojave.
Yesterday my PC started rebooting right after start. I did not install, upgrade or change anything that could explain this behavior. Even more strange, all of a sudden (maybe after 10 reboots) system started working again. (Sometimes I could still work for a couple of seconds before system rebooted and I used this short moments to free some space on boot disk, which was pretty much full.) Yesterday I thought, that freeing disk space was the reason, why the system started working again and it worked perfectly for the rest of the day - even after manual reboots.
But today the system reboots constantly - even quicker than yesterday, so that I can not do anything.
The reboots only happens after I log in with the user. Before user login, the system can show the user login screen without rebooting. Also I found out, that the reboot is much quicker, when the network cable is connected - than it sometimes even reboots before user login screen.
I have Windows installed on the same SSD on a different partition. The system is completely stable when running Windows and I have done all kinds of hardware test, without seeing any issues.

Also, I do not get any hints when reading the spindump of the shutdown_stall_2020-09-02-114900_kermit.shutdownStall
