--- Comment #6 from Jim Bride <jim.bride at linux.intel.com> ---
I tried to reproduce this on my SKL NUC running 4.8.0-rc3 pulled today using
the following:

jbride at jbride-snuc:~/src/intel-gpu-tools/tests(2001)$ sudo ./kms_pipe_crc_basic
--run-subtest suspend-read-crc-pipe-A
IGT-Version: 1.15-g6f002ab (x86_64) (Linux: 4.8.0-rc3-082516+ x86_64)
rtcwake: wakeup from "mem" using /dev/rtc0 at Thu Aug 25 21:08:37 2016
suspend-read-crc-pipe-A: Testing connector DP-1 using pipe A
Subtest suspend-read-crc-pipe-A: SUCCESS (1.197s)

And to make sure things were ok:
jbride at jbride-snuc:~/src/intel-gpu-tools/tests(2003)$ dmesg | grep ERR
[    0.332913] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM

It would be nice to know the complete configuration of the systems that
reproduce this bug, including the make and model of any displays involved
(external and internal.)
