El Capitan 10.11.4 - panic at "starting darwin x86_64"

[IronMann]

I couldn't resolve my installation problem with updating in place from Yosemite to El Capitan 10.11.4.

So I went with a USB install instead - which seemed to work. But I can't boot from the OSX instance on my ssd.

I get a panic just after it says, "starting darwin x64"

Not sure what to make of this and any searches on tonymacx86 yields references to older OSX version installs.

Any help is appreciated. I can tell it to boot from the USB drive but it just starts the installation process from scratch.

Thanks,

-I

Update. I disabled SIP and now it just restarts the machine just before it's about to launch El Capitan. This reminds me vaguely of a build I did a couple of years ago on an hp laptop where I had to copy the Mach kernel from the USB to the hard disk to get it to launch properly.

note that I updated my hardware profile. My setup is basically a customac pro build taken from this sites buyer guide.
