--- Comment #4 from Qingshuai Tian <qingshuai.tian at intel.com> ---
I have finished the bisect, and the result shows:

24576d23976746cb52e7700c4cadbf4bc1bc3472 is the first bad commit
commit 24576d23976746cb52e7700c4cadbf4bc1bc3472

    drm/i915: enable VT switchless resume v3

    With the other bits in place, we can do this safely.

    v2: disable backlight on suspend to prevent premature enablement on resume
    v3: disable CRTCs on suspend to allow RTD3 (Kristen)
