Still incomplete however, now it is OWATCH timeout.

from IRC:
<tursulin_> marta_, cpuhotplug I've reported it yesterday to lkml but no replies yet. I've reproed the failure with pure cpu offline/online loop - no i915 - https://patchwork.freedesktop.org/series/37744/.

    tests/perf_pmu: Skip hotplug test on Broxton
    
    Apollolake machine in the shards cannot bring the CPU0 back online so
    skip the test on all Broxtons for now.
    
    v2: Fix inverted check.
    v3: igt_skip_on. (Chris Wilson)

Comment 4 Marta Löfstedt 2018-02-22 11:57:47 UTC 
I will archive the bug from cibuglog. However, it should be kept open. This issue should be fixed by new BIOS version.
Comment 5 Martin Peres 2018-04-20 14:17:26 UTC 
Just to clarify: This bug is kept open because we need to make sure this issue gets fixed in core and/or BIOS.

Comment 7 Jani Saarinen 2018-06-01 09:58:00 UTC 
new BIOS or new BIOS + latest drm-tip fixed this.
Comment 8 Jani Saarinen 2018-06-01 09:59:38 UTC 
Patch from Tvrtko is just enable testing again on that test on APL.
