Last year we saw a PS4 Kernel Exploit and List of PIDs followed by a PS4 Filesystem Root Dump and now PlayStation 4 hacker esjonne12 Sda shared a video of that PS4 DevKit / TestKit developer kernel dump running on a PC. 
To quote from jonttufin's posts on the demo video: I booted PS4 DevKit kernel on my PC
You remember that testkit root dump that leaked 2015 I ran that kernel on my PC
Sorry for crappy quality
To boot it download Test-Kit-FW-00.820-Root.rar from somewhere on google, extract all folders inside adm folder to isolinux bootable usb stick overwrite isolinux.cfg, i used YUMI-2.0.2.6, if you use yumi you need to copy those files to /multiboot folder on usb, commands to run the kernel
1 configfile /multiboot/grub2_200
2 kfreebsd /multiboot/orbisys
3 kfreebsd_loadenv /multiboot/orbisys-root.cnf
4 kfreebsd_loadenv /multiboot/orbis.cnf
5 kfreebsd_loadenv /multiboot/orbis-itf.cnf
6 boot and now its booting.
ps it wont support ps2 keyboard
Also below is an older PlayStation 4 development system demo video for those interested:
