System Environment:

igt/kms_flip/flip-vs-panning-interruptible fails on ILK and HSW on -nightly and
next-queued(c79057922ed6c2c6df1214e6ab4414fea1b23db2)

It's a regression bug:
good commit: 04feced98a434c7046108671dc5b6f50f3b63ed7
bad commit: c79057922ed6c2c6df1214e6ab4414fea1b23db2
We will bisect it later
