PCI configuration begin on Vaio laptop

[jl4c]

Hi all,

 

I've this problem:

 

- OS X boot fine, but in verbose mode the display doesn't show nothing after "PCI configuration begin".

- When i boot in single mode, the system stuck at "PCI configuration begin".

 

I can boot in single mode only if i rolling back the ACPIPlatform and IOPCIFamily kexts.

 

But i am searching for a vanilla solution for this issue (DSDT)

 

This is a extract of my PCI0 section of my DSDT:

 

Device (PCI0)
 {
	 Name (_HID, EisaId ("PNP0A08"))
	 Name (_CID, EisaId ("PNP0A03"))
	 Name (_ADR, Zero)
	 Method (^BN00, 0, NotSerialized)
	 {
		 Return (Zero)
	 }
	 Method (_BBN, 0, NotSerialized)
	 {
		 Return (BN00 ())
	 }
	 Name (_UID, Zero)
	 Method (_PRT, 0, NotSerialized)
	 {
		 If (PICM)
		 {
			 Return (AR00 ())
		 }
		 Return (PR00 ())
	 }

 

This is a extract of my system log:

 

[ PCI configuration begin ]
PCI configuration changed (bridge=12 device=1 cardbus=0)
[ PCI configuration end, bridges 7 devices 15 ]
[ PCI configuration begin ]

FireWire (OHCI) VendorID 1180 ID e832 PCI now active, GUID 0800460303484d03; max speed s400.

 

If some one knows a fix for this, please let me know.

 

Muchas gracias chicos

Apart to "vanilla solution", because none of them fixes by DSDT worked for me (my MSI motherboard), it can be solved from /Extra/o.c.B.p

 

Kernel Flags

npci=0x2000

 

or npci=0x3000

Good Luck.

Thanks Juanerson, but that flags doesn't work for me

I would suggest using npci=0x3000. it seems to work for my vaio. VPCEB16FG. i have complete system up and running, full with QE/CI. I used iAtkos ML2. use flags, "-v -f npci=0x3000 USBBusFix=Yes GraphicsEnabler=No cpus=1" to install. without quotes of course.
