Kernel panic in old MacBook Pro after upgrading to El Capitan

I'm trying to get my old 15-inch MacBook Pro (Mac-F42D86C8) from late 2008, back to life.

I installed El Capitan operating system upgrade and since then, everytime I boot I reach a kernel panic and the laptop reboots again and again.

I've managed to start the system in safe mode and read the kernel panic information (attached below). However, It looks like a problem with the graphics system. I've tried following some online troubleshooting manuals without much luck.

I've reinstalled El Capitan several times without better results. I'm not sure why it works in safe mode.

UPDATE 2016-01-03

I've removed the HD from my MacBook Pro from 2008 and put it today in a White Macbook I have at home and I've been able to finish the El Capitan install and get it working without issues.

So I've removed the HD from the White Macbook and put it back in the MacBook Pro 2008 and It has booted correctly the first time. I've started Safari, I've gone to youtube and when starting to watch the first video, it has kernel paniced. Now I'm unable to boot the computer again.

BTW, I'm using a 3rd party Hard drive, but I believe it's not the issue because it works flawless in the White Macbook. My understanding is the issue is related with the two graphic cards, and I'm unable to upgrade the EFI as suggested by @kenjikato

2nd UPDATE 2016-01-03

Every time I boot my HD in my white MacBook and then put it back in my MBPro it works the first boot.

This time I switched to high performance in Energy Saver and it did work. However seconds after that, the screen started to turn purple. It looks like something is wrong with one of these graphic cards.

You can see the video here

3rd UPDATE 2016-01-04

I've managed to boot sometimes in El Capitan, however it's quite unstable, and the operating system doesn't seem to remember the high performance mode after a crash. This is another kernel panic I captured today, I believe it's different enough from the previous one.

Solution 1:

I think I found your problem. It appears that you have one of the faulty Nvidia 9400m graphics cards in your computer. If you search on your model you will find lots of discussions (Apple Support, GoodBytes) about this system, and problems with the 9400m graphics card.

If you were running your system in “High Performance” graphics mode, then the system relied on the 9600m graphics card rather than the 9400m. So you would not have seen the dreaded flickering and green flash so many people reported on.

There is a fix, Apple released an EFI Firmware Update 2.8 for several systems including your MacBook in 2012.

But if you read through your kernel panic log you will see that you only have the 2.0 EFI Firmware in installed.

com.apple.driver.AppleEFINVRAM  2.0
com.apple.driver.AppleEFIRuntime    2.0

Hence the kernel panic you are seeing.

I would suggest that if you made a backup before you tried updating the system (you did make a backup right?) that you:

  1. Boot your computer from your Snow Leopard pre-upgrade backup.
  2. Go to  -> System Prefs -> Energy Saver and set your graphics card to High performance. enter image description here
  3. Try installing the EFI Firmware Update 2.8 from Snow Leopard.
    NOTE: The installer will ONLY work from Mac OS X 10.5.8, 10.6.8 or 10.7.3. according to the Apple website.
  4. Reboot to the internal drive, and the new El Capitan OS you already installed.

You might have to rerun the El Capitan installer again to get things working, but I have a feeling that you should be able to just boot up into El Capitan.

I hope this solves your problem.

ADDITION:
One additional workaround for this problem came to me from a friend.

You can try and disable (in Mavericks 10.9, Yosemite 10.10 and El Capitan 10.11) the Automatic Graphics Switching if you can boot into the the updated OS, and get to the System Prefs. This may disable the 9400m enough that you “might” not see the kernel panic again.
