b31k Posted August 18, 2017 Share Posted August 18, 2017 (edited) Hello My system isAsus Z170-P Motherboardi5 6600K ProcessorNVIDIA GeForce GTX 1050 Ti 4095 MBBe-quiet 500W PSUCrucial 16 GB 2400 MHz DDR4BIOS:xHCI Handoff enableSerial Port disableSATA AHCI modeIOAPIC 24-119 Entries (enable y disable) two mode stuckI 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.
