uname -r
	5.3-BETA7

sysctl hw.ata.atapi_dma
	hw.ata.atapi_dma: 0

I have the same laptop and the same problem, I solved using

	device atapicam
	device scbus
	device cd
	device pass

and cutting out

	device atapicd 

During the bootstrap I have 5/6 sec. of pause, after that 
all works well and I can use the DVD drive by the device /dev/cd0
