"busy timeout, (60s), kextd wait(0): 'IGPU'"

Hello guys, I'm having a problem booting to my macOS Sierra, every time I power on my laptop it's always showing "busy timeout, (60s), kextd wait(0): 'IGPU'. I've done patching DSDT and SSDT, change everything from GFX0 to IGPU, but it still stuck, pls help. Note : Currently using Laptop ASUS X455LA, 6GB of RAM, Intel HD 5500, Core i3-5010U. Thanks in advance, sorry for my bad english since it's not my native language.
