Trouble with Lenovo 00JT494 / Foxconn TH77H649.00 (BCM4350)

[zogthegreat]

Hi Hervé,

 

For some reason, I'm not getting the strings right for my E7450 and I was hoping that you could help me. I grabbed as much information as I could from both Windows and Linux.

 

Here is the details from Windows:

PCI Slot 3 (PCI bus 2, device 0, function 0)

PCI\VEN_14E4&DEV_43A3&SUBSYS_075A17AA&REV_08\0000C7FFFFC1606D00

Hardware ID's

PCI\VEN_14E4&DEV_43A3&SUBSYS_075A17AA&REV_08
PCI\VEN_14E4&DEV_43A3&SUBSYS_075A17AA
PCI\VEN_14E4&DEV_43A3&CC_028000
PCI\VEN_14E4&DEV_43A3&CC_0280

Bus number

00000002

Location paths

PCIROOT(0)#PCI(1C03)#PCI(0000)
ACPI(_SB_)#ACPI(PCI0)#ACPI(RP04)#ACPI(PXSX)
 

 

And from Linux:

My problem is getting the device string like you have in your example that I found here:

 

 

Thanks!

@zogthegreat

try this

config.plist.zip

[Hervé]

Location paths
PCIROOT(0)#PCI(1C03)#PCI(0000)
ACPI(_SB_)#ACPI(PCI0)#ACPI(RP04)#ACPI(PXSX)

-> Your Windows info clearly shows your card attached to ACPI device RP04@1C,3->PXSX@0. As such, you'll inject your properties under PciRoot(0x0)/Pci(0x1c,0x03)/Pci(0x0). You'd have also seen this using IORegistryExplorer.

[zogthegreat]

@Jake Lo I tried your config.plist and I got a kernel panic on boot, (first two attached images).

 

@Hervé, Yeah, that's the information that I am adding to the config, but for some reason my wifi isn't showing up, although the bluetooth is. Although you do bring up an important point. If I'm going to be using OS X, I need to learn the tools for it. 

 

I'm including a copy of my config.plist and my dump file. I had an error when generating the dump file:

Spoiler

IOREG dump failed. Retrying by increasing delays...\
Increased delay by x2 times. Retrying...\
IOREG dump failed. Retrying by increasing delays...\
Increased delay by x3 times. Retrying...\
IOREG dump failed. Retrying by increasing delays...\
IOREG dump has failed 3 times. Dumping generic IOREG report instead.\

Try this one. Or just remove the Wifi FakeID and add to boot arg

brcmfx-country=#a

config.plist.zip

[zogthegreat]

@Jake Lo

 

Thanks for the config. I did manage to get the card working by editing my config.plist properly. However, when the DW1820a is installed, I get random freezes and complete system lockup's. I just tried your config.plist, and I get the same results. Without the card, the system runs smooth.

 

I did another system dump that I will attach below, along with the config.plist that I managed to get working. I'm going to do some hardware testing to make sure that the problem isn't the actual wifi card. Rare, but it does happen.

Try 4331 instead of 4353.

Re explore IOReg with this, the raw txt file is hard to read

 

[zogthegreat]

Thanks Jake Lo. I tried changing 4353 to 4331 as you suggested, but the problem persists, (I had to switch computers to finish writing this sentence!). I did a dump with the version of IORegistryExplorer that you suggested and attached the output below.

 

I'm wondering if I have a driver conflict. I keep noticing "AirPort_Brcm4360" in the output when I'm booting.  I'm slowly dumping the log files. I'll post up if I find anything in there.

Remove FakePCIID.kext + FakePCIID_Broadcom_WiFi.kext

[zogthegreat]

OK, I'm looking through the "system_report_crash", I found this:

I'm Googling the details now, but I am also posting the crash report. The log file "system_report_kernel_panic" also has a similar error:
