S4 also failed to resume after removing i915, I noticed that the screen is not
black, and the machine is reachable. I said it failed, because my script
stopped, and the screen output is strange. I loop running S4 test for two
times, the first time it failed at 9th round, the second time it failed at 6th
round.
There's quite a little things in dmesg, I pasted it here:
