I'm currently running iOS Mavericks (10.9.5) on my Macbook Pro 13" (Mid 2012). When I tried to upgrade to El Capitan, I got the Kernel Panic screen immediately after the first reboot.
I performed a hardware test, but no problem was detected. The HD is brand new and working just fine. The camera and one of USB ports are not working at all, but these issues may be unrelated.
Please see attached a copy of the screenshot. Any ideas on what might be causing the issue?
Thanks
