Help! ACPI Panic (XHC RHUB Namespace Failure), I can't figure it out...

Hi there,

 

If anyone could help I'd be very grateful, I'm trying to move from Clover to OC but have hit a brick wall for the last 2 days.

 

It's an ACPI table error: SB_.PCIO.XHC_RHUB.HS11, Namespace lookup failure.

Skylake Build:

OpenCore 0.5.9

Mojave 10.14.6, iMac17,1

Asus Maximus Hero VIII

6700K

 

I've attached the config.plist and ACPI folder.

 

EFI Drivers: OpenRuntime.efi and HfsPlus.efi

Kexts: IntelMausi, Lilu, VirtualSMC, Whatevergreen

 

Things I've tried...

 

1) Clearing NVRAM (as it was previously booted by Clover)

 

2) Hackintool USB Mapping: both the SSDT files and the USBPorts.kext

 

3) USBInjectAll.kext (with and without SSDT files)

 

4) SSDT-RHUB.aml. This seems to be directly involved, spent a long time with this but with no luck.

 

I followed this guide:

 

https://dortania.github.io/Getting-Started-With-ACPI/Universal/rhub-methods/manual.html

 

Everything is XHC in my DSDT, except these definitions at the top (line 72 and 73):

 

    External (_SB_.PCI0.XHC_.DUAM, MethodObj)    // Warning: Unknown method, guessing 0 arguments
    External (_SB_.PCI0.XHC_.RHUB.INIR, MethodObj)    // Warning: Unknown method, guessing 0 arguments

 

So I edited the SSDT-RHUB.dsl to this:

 

/*
 * Goal of this SSDT is to shut off the RHUB to force macOS into
 * manually building ports when the ACPI is screwed up
 */
DefinitionBlock ("", "SSDT", 2, "DRTNIA", "RhubOff", 0x00001000)
{
    External (_SB_.PCI0.XHC.RHUB, DeviceObj) // Full pathing to RHUB, change to yours

        Scope (_SB.PCI0.XHC.RHUB) // Full pathing to RHUB, change to yours
        {
            Method (_STA, 0, NotSerialized)
            {
               If (_OSI ("Darwin"))
                       {
                          Return (Zero) // This disables the device only in macOS
                     }
                     Else
                     {
                     }
           }                    
        } 
}

Which results in this AML version:

DefinitionBlock ("", "SSDT", 2, "DRTNIA", "RhubOff", 0x00001000)
{
    External (_SB_.PCI0.XHC_.RHUB, DeviceObj)

    Scope (_SB.PCI0.XHC.RHUB)
    {
        Method (_STA, 0, NotSerialized)  // _STA: Status
        {
            If (_OSI ("Darwin"))
            {
                Return (Zero)
            }
            Else
            {
            }
        }
    }
}

But I get the same error. 

 

I'm at a complete loss, can anyone help?

I hit the same wall converting a working OC EFI I built to work on a new machine using a new microarchitecture. The ACPI table which was not loading for me was an OEM SSDT with TableId `Dell__Bl`. I added this to the ACPI delete section and was able to boot successfully. In my case it was an SSDT from Dell which does nothing more than describe where USB ports are physically located on the machine and I saw no harm in unloading it.

 

Search through the decompiled SSDT/DSDT files for the table path in the error messages and then see if you can unload it and get past that point.
