drm.debug=7 dmesg?

(In reply to Chris Wilson from comment #1)
> drm.debug=7 dmesg?

Only reproduce once as above and didn't save dmesg.
I run it more than 10 cycles just now, I can't reproduce the fail. 
It also fails when run automation testing, the log as below:

Dmesg:

Tested it on the latest nightly kernel and igt.
This issue does not exists on BYT, but it still exists on BSW.

> Reproduced on BSW with 4.3.0-rc2-drm-intel-nightly

Reproduced what? Always attach fresh output so that we can confirm it is the same bug, and hopefully gain further insight.

gem_cpu_reloc@basic and full are Pass with last setup on BSW-M.
Let's check on BYT and SKL before closing it.
