my test machine has a cold boot failure rate of about 80% _if USB Stuff is plugged in_
Without USB Stuff it is about 90% cold Boot ok (at the moment with 11.4 20F71)
MP4.1 Single, 3.46 QuadCore, 24GB Triple Channel Ram, 144 rebuilt firmware, Kepler GPU, Sata SSD as Slave, Apple AHCI Blade SSBUX as Boot Volume in PCIe Slot 2, always booting verbose.
Bootloader makes no difference, swapping from OCLP to RefindPlus to bare Metal OC, even preRelease of 0.70, spoofing or VMM.
To remember: Even flashed an ancient Firmware with APFS Loader via RefindPlus made no difference.
Others with 4.1 can't barely boot, so it's not the SMC Firmware.
Now loading 11.5 Beta to check if there are different results...
Edit: Worked, updated from 11.4 RC to 11.5 Beta 1 (had USB plugged off during update)

Hopefully a kernel patch done with OpenCore, if a patch is found (and currently that's a big cautious if).
With 11.3 on the same Apple SSUBX drive, I have a very low rate of successful booting...
Booted 11.5 Beta 1 with my killer test (4 USB thumb drives in) and it hung on crypto
tried it before with USB and a DVD in, ok.
after the hung seen on the screenshot it hung on Ethernet. Thats the usual point since 11.3 for me when it hangs with USB.
next cold boot without USB it was fine.

the most guys what cant barely boot have dual CPU Boards.
Maybe give cpus=1 a chance or plug a single cpu Board in if you have one.
I can try with a Dual 5.1 Board, dont mind the fan noise for a quick test...
same machine with dual cpu board acts exactly same (DVD was still in, USB unplugged)

ok, found something noticable:
had some rendering glitches with Safari and the Kepler GPU and tried
agdpmod=pikera
now I could cold boot 3 times in a row with my killer test 4 USB Sticks (plus DVD in).
maybe not relevant but worth a try.

I believe @tsialex can explain that. It's related to a buildup of writes to the NVRAM chips that end up damaging them if not mistaken. He can explain it better that I can. The NVRAM section on the cMP is very small and fills easily. When you fill NAND chips up and hit them with a lot of writes it causes them to wear and degrade over time. He offers a service that I believe can help prolong the life of the cMP by clearing it out from time to time. Opencore also has some safety measures built into it that may help as well but I can't say for sure.
Could you elaborate? Was that in your config.plist? In mine the relevant part is:
XML:
<dict>
<key>agdpmod</key>
<data>
cGlrZXJhAA==
</data>
<key>rebuild-device-tree</key>
<data>
AA==
</data>
<key>shikigva</key>
<data>
UA==
</data>
<key>unfairgva</key>
<data>
AQAAAA==
</data>
</dict>"ioreg -l | grep agdpmod" in terminal returns:
"agdpmod" = <"pikera">
"agdpmod" = <"pikera">
Understanding the OpenCore Data variable settings
Not really answering your question. But for info, Hackintool can do all the conversions we usually need.

setting the boot-arg in OpenCore (I used OCLP 0.1.5 package)
in config.plist
Code:
<key>boot-args</key>
<string>keepsyms=1 debug=0x100 -v agdpmod=pikera</string>validation:
Code:
nvram boot-args
boot-args keepsyms=1 debug=0x100 -v agdpmod=pikera

What you display is an error message with any debug settings enabled? Or it just shows on your screen when you reboot, with a standard OC configuration.
I have dual CPUs with no boot issues. I'm interested if anyone matching my procs and ram size on a 2010 Mac with MX25L3205D SPI has boot issues.

The sleep issue is definitely network service related but unfortunately I need those services enabled. I had a workaround on Catalina but unfortunately that no longer works on Big Sur... With this problem looking like it won't be solved anytime soon maybe it's time to go back to Catalina for now
It's been an amazing journey with these machines, with many great surprises. Who would have thought getting GOP support this late in the game? So I wouldn't despair just yet. Of course, that's an enthusiast's perspective. In reality, the future looks like it's going to be M1, and your RX 580 alone can fetch a pretty penny at this moment.
