I tried a Toshiba R950 which boots and images. A Toshiba R840 which is the laptop I was trying to take an image from will boot to the PXE menu and let you choose an option but will then just give a black screen. I did try the kitchensink kernel but same issue. I gave up in the end and didn’t take the image but it would be useful if I could get it to work so I don’t have to manually rebuild in the future.
