Have you used git skip or why exactly could bisect not nail down the commit
further?
The first two patches should be unrelated, but the 3rd one changes the default
for power wells on haswell. Can you please retest latest -nightly with
i915.disable_power_well=0 added to your kernel cmdline?
Also is the failure exactly reproducible, i.e. when running this subtest it
always fails with this output?
Beginning blocking-absolute-wf_vblank on crtc 5, connector 9
1920x1200 60 1920 1968 2000 2080 1200 1203 1209 1235 0x9 0x48 154000
.run_test_step:749 failed, ret=-16, errno=16
Aborted (core dumped)
The important part is "crtc 5, connector 9". If the failure happens when
testing other crtcs/connectors (on this specific machine, connectors are not
numbered the same way depending upon the exact board configuratino) this would
be very important to know.
Note to self: Connector 9 here is VGA on the LPT pch.</pre>
