Result flipflops are handled through cibuglog which connects (test,host) 
to fd.o bug. There is no bug for PNV for this issue, it's quite rare as 
can be seen from

https://intel-gfx-ci.01.org/tree/drm-tip/fi-pnv-d510.html

(the bug seem to appear after failure on gem_ringfill at basic-default-hang)

So yes: in this case CI gives misleading result, but that can be easily 
checked (by human) from history. Work is being done towards cibuglog-ng 
that is much easier to use to detect and create bugs like this, and has 
better knowledge about previous runs.
