It also fails on HSW.
Comment 3 Chris Wilson 2014-12-31 10:47:16 UTC 
[  218.098896] gem_exec_bad_domains: starting subtest conflicting-write-domain

Buggy cmd parser? Buggy coherency?
Comment 4 Elio 2015-10-01 15:22:22 UTC 
This bug is reproducible on BDW-U on first run with the following configuration, specially with gem_evict_everything@major-normal.

I'll run it by it self and going to attach logs as soon as possible

Which test? This bug is about the gem_exec_bad_domains failing after a successful gem_evict_everything run. If you have gem_evict_everything failure, please open a separate bug.
Comment 8 Chris Wilson 2016-10-22 09:36:45 UTC 
Buggy coherency.
