Acer 4810TG has very limited BIOS options so the only meaningful thing I could modify was the USB boot. Not much else to play with anyway.

The Kernel Panic says:
"cpu 0 caller 0xffffff80002bfb6f): "should have 1 Thread but only found 2 for Die 0"@/sourcecache/xnu/xnu-1456.1.25/osfmk/i386/cpu_threads.c:1131

system model name is MacPro3,1
