On my ASUS Transformer Book T100HA, the built in DSI display fails to display
any image right after KMS takes over from efifb. The backlight remains on.
Please see attached for kernel log (drm.debug=0xe).
I am unable to obtain a VBIOS dump. Kernel says:
0:02.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xe725

Always.
