 I think that I have the same problem (but with haswell)

 When I load manually i915kms I don't have any problem but there is still some error message printed :

drmn0: <Intel Haswell (ULT GT2 mobile)> on vgapci0

drmn0: taking over the fictitious range 0xc0000000-0xd0000000

 When loaded via loader the kernel hangs after this line :
