E6430: Kernel Panic with Hervé's E6230 guide

I'm sorry, I couldn't help myself and tried Jake Lo's guide with the E6230_A11 boot pack. It works almost perfectly, I couldn't wish more.

Though there is a tiny issue with sleep, or rather two different issues. First, it seems like when I use the Fn+F1 hotkey, it switches to some other mode, which doesn't work properly (unlike automatic sleep or using the menu option). And the second one is minor, but annoying: after the laptop wakes up, the HDD indicator starts blinking constantly and doesn't stop. It doesn't behave like that before sleep, and I'm pretty sure it's not i/o activity either. Have you encountered such an issue?

Otherwise, the system seems to work perfectly. I'm extremely grateful for what you're doing here in this community.

Fn-F1 does not properly put E6230 to sleep under Sierra; it seems to actually kick hibernation instead. So the laptop will actually shutdown and a sleep image file will be created.

 

It's probably a side effect of some incompatibility with the generated CPUPM-related SSDT. I had fixed a similar issue on the E6440 under Yosemite. Until we suss this out, proceed as JakeLo recommends: close the lid or use Apple menu option.

You can adjust the DSDT of a HiRes HD4000 E6430 to your LoRes model by the following simple modification of the _DSM method of the iGPU device located at address 0x00020000:

  • set DualLink from 1 to 0
  • set layout-id from 0x01660004 to 0x01660003

In ACPI code, this translates to:

Before

                        "AAPL00,DualLink", 
                        Buffer (0x04)
                        {
                             0x01, 0x00, 0x00, 0x00                         
                        }, 
                        "AAPL,ig-platform-id", 
                        Buffer (0x04)
                        {
                             0x04, 0x00, 0x66, 0x01                         
                        }, 

After

                        "AAPL00,DualLink", 
                        Buffer (0x04)
                        {
                             0x00, 0x00, 0x00, 0x00                         
                        }, 
                        "AAPL,ig-platform-id",
                        Buffer (0x04)
                        {
                            0x03, 0x00, 0x66, 0x01                         
                        }, 

You can also remove the entry for "AAPL00,DualLink" entirely.

Thanks for the tip. I just tried it with the E6530_HD4000_Only.zip bootpack, it seems like the blinking has stopped. Though I noticed few other problems, and they're common for all three DSDTs I've tried so far (including my native DSDT without patches I extracted with Clover).

First, the webcam doesn't work. It's weird, because I remember that it definitely worked few days ago when I tried to install Sierra. I specifically checked it during account setup.

Second, one of 3 USB ports doesn't work. I added PCIID_XHCIMux kext to my Clover, as you noted in your guide, but it didn't help.

And the third one is really minor. I got native brightness control, but only for decreasing (Fn+F3 instead of Fn+Down as marked on my keyboard). I didn't manage to find the other combination for increasing brightness. In my DSDT I have the same value for PNLF device _UID as you mentioned in your guide. Does it work for you? If so, what keys are dedicated for it on your keyboard?

  • Fn-F3 for reduce brightness
  • FN-Insert to increase it

Your Webcam is USB-internal and the trouble you experience is linked to your other USB issues. Basically, you need to rename DSDT EHCx devices to EH0x and use a USB injector. This matter is widely discussed and covered on all forums including this one. Do a Search on the matter.
