Tested in a loop, it is about 20% reproducible.

Please try the attached igt patch to gain better information about what goes on, and provide the test output.
Comment 3 Jani Nikula 2016-04-25 12:16:02 UTC 
Oh, and if this only happens on KBL, it's possible it's because of the display on the RVP, and not because of the driver.
Comment 4 Daniel Vetter 2016-05-04 15:14:11 UTC 
I've also seen this just happen on BDW in a CI run.
Comment 5 Daniel Vetter 2016-05-09 07:18:05 UTC 
Also just spotted on bdw.
Comment 6 Luis Botello 2016-05-20 22:03:06 UTC 
Issue still present on KBL U with the following config:

Comment 8 Jani Nikula 2016-06-13 14:34:48 UTC 
Is this reproducible if you set i915.enable_psr=0 module parameter?
Comment 9 yann 2016-06-20 17:03:48 UTC 
Luis, can you confirm with i915.enable_psr=0?
Comment 10 Luis Botello 2016-08-01 20:43:40 UTC 
Issue is still present on KBL even with kernel command i915.enable_psr=0 this is my config:

Luis et.al, can you check if the fail exists nowadays. Based on the https://intel-gfx-ci.01.org/CI/igt@kms_sink_crc_basic.html I would say that for test case FAIL we can close this bug - there is another one for ILK (bug 100411). For SIP with "Last errno: 25, Inappropriate ioctl for device" and/or "Sink CRC is unreliable on this machine. Try manual debug with --interactive-debug=no-crc, Last errno: 9, Bad file descriptor" (see https://intel-gfx-ci.01.org/CI/CI_DRM_2412/fi-kbl-7560u/igt@kms_sink_crc_basic.html) let's open a new bug(s).
