[Solved] Still waiting for root device randomly

[b31k]

Hello

My system is
Asus Z170-P Motherboard
i5 6600K Processor
NVIDIA GeForce GTX 1050 Ti 4095 MB
Be-quiet 500W PSU
Crucial 16 GB 2400 MHz DDR4

BIOS:

xHCI Handoff enable
Serial Port disable
SATA AHCI mode
IOAPIC 24-119 Entries (enable y disable) two mode stuck

I can not build a robust and stable system, The system Sierra is already installed but when I restart or shut down, I get the error Still waiting for root device error, but after too many reboot ( from 2 times to 9) start correctly or other times leave too minutes, with prohibited symbol and finally starts.
Once started recognised correctly HDD.

Also I tried with a new  EVO860 nvme SSD , but I have the same problem.

 

 

I dont know because sometimes yes sometimes no, the system stuck in this error

I add some information files and logs.

 

sudo touch /System/Library/Extensions && sudo kextcache -u /

kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext HackrNVMeFamily-10_12_6.kext

kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext FakeSMC.kext

kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext BrcmPatchRAM2.kext

kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext BrcmFirmwareRepo.kext

 

thank you.

 

Solution by Rehabman;

Extracting my native/clean DSDT using Clover F4.
and check with diff DSDT file.

My SystemMemory addresses in DSDT are mismatched:

SPEEDY-NUCatched rehabman$ diff ../origin/ ../patched/|grep SystemMemory
< OperationRegion (GNVS, SystemMemory, 0xC74EC000, 0x06D5)
> OperationRegion (GNVS, SystemMemory, 0xC74FE000, 0x06D5)
< OperationRegion (CPSB, SystemMemory, 0xC6CC0F98, 0x10)
> OperationRegion (CPSB, SystemMemory, 0xC6CD2F98, 0x10)

and other mistake in OperationRegion(PNVA,SystemMemory,PNVB,PNVL)

< Name (PNVB, 0xC74F1018)
> Name(PNVB,0xC7503018)

My system after too many month , keep stable the still waiting error no appear again, it seems that the problem was with the memory addresses in my DSDT.
