help on CI fail for patchwork 21938

[jim.cromie at gmail.com]

this patchwork CI test is failing.

https://intel-gfx-ci.01.org/tree/drm-tip/Patchwork_21938/fi-kbl-soraka/igt@i915_selftest@live@evict.html

I dont understand what went wrong, but I dont see how patchset could
be involved,
it is drm.debug code, and I dont see evidence that it is even active.
It would have to be explicitly enabled from user-space, via:
echo 0x05 > /sys/module/drm/parameters/debug

I will be resending patchset here, for another pass thru CI,
so Im looking for hints more than specific fixes.
